How To Fix A Noisy Fuel Pump On A Chinese Diesel Heater - Quiet Fuel Pump And No More Ticking Noise
Vložit
- čas přidán 4. 04. 2020
- My Chinese diesel heater had a noisy fuel pump and was ticking with every pulse.
In this video I show the steps I have take to reduce this noisy fuel pump and make it a lot quieter.
So if you want to make you diesel air heater quieter and reduce the ticking noise try the thing s I suggest in the video.
Making a quite fuel pump for a diesel heater will not cost a lot of money as well!
This Chinese diesel heater is fitted in my motorhome and it works perfectly - a good investment.
Thanks for watching.

Appreciate you cutting one open, that’s really interesting
Yes, cutting the pump is the coolest thing I have seen in all these heater videos!
Finally an educated diy video, i have watched hundreds of backyard hacks videos claiming how to get rid of the tick. It can't be done, but the front bar experts will keep claiming they know the answer.
The nature of the pump itself is certainly not conducive to being anywhere near silent or even vaguely quite...!!
Plus the diesel oil is really the only form of cushioning inside the pump, so really not possible to do anything other than try to quieten it down by masking the ticking pulse..!?
I've actually got quite used to now and any ticking noises just blend into the background...🙄
ATB,
Steve
Everyone should thumb this up just for the cut away of the pumpl
Thanks for cutting one open! I watched a video on this yesterday and have been wondering why it makes that ticking sound and how it relates to pumping fuel. Great video!
Many thanks for this. Just installed one of these on my camping van and that noise drove me almost insane! I decided to reroute the fuel line and pump and put it outside of the vehicle. There is good insulation of two layers of plywood plus a good two inches of polystyrene on the underside, plus the carpet etc to deaden sound. A bit of a job but well worth it.....I can sleep peacefully without counting clicks! I now need to weather seal the pump....and buy a spare just in case...but here in the South of France wet weather is rarely a problem...and in winter it is frozen solid in the Pyrenees..... Thanks again, Martin
So I completely silenced mine. You can't hear anything in space so I created a small PVC vacuum chamber and the pump sits inside. The inlet and outlet hoses and wires are silicone sealed and I incorporated a Schrader valve to pull vacuum.Easy to make. You can hear it go silent as the vacuum increases. simple, cheap, effective. No one can hear you clicking in space. Odd when it's totally silent. I'll post a video of it on my channel. Enjoy.
plz make a video
The lack of a video determined this was a lie
Vacuumed and silicon sealing. You are full of crap. God will judge you.
Lol
Maybe Randy took and died while the testing periods? R.I.P Randy!😊
If you angle the pump 45 degress, the internal mechanism is fully lubricated.
Placing the pump below the fuel tank allows full immersion too
I also place mine in wool insulation, in an aluminium box, screwed to a secure point in the vehicle.
Excellent video! Noises like that can drive you insane once you start paying attention. ATB Marc-Belgium.
I got a little bit more fancy on my sound deadening.
I got myself a piece of 3 inch pvc rain drainage pipe and two pvc end caps, a couple of fuel line grommets and some rock wool insulation. I stuck the pump inside the pipe surrounded by insulation. the end caps I press fitted in place with a couple of small screws to hold them onto the pipe. I mounted the pipe with some down pipe brackets. The sound is there but hardly noticeable... even when it is at full blast...
Not sure which I like better, the content or te fact that you are quick, concise, on point. Thanks
I have tried everything , even put the pump in a PVC pipe and filled with expansion foam The only way to silence that POS is to rip it off the mount and trow it in the nearest river !
I unscrewed my pump from the bulkhead. It is hanging via a cable tie loosely looped to a sob shock forces. Worked well.
Great video, thank you for putting it out there. I was wondering about how to get rid of that noise 👍
Thanks for addressing this annoying problem.
Thank you for the cut away and description of the workings of the fuel pump. Very interesting.
Very welcome, glad it helped.
ATB, Steve
Thanks for the video and glad you were able to quiet your pump! My pump is underneath our van and these cheap chinese fuel pumps are incredibly loud, especially at start up. I've purchased one of the rubberized covers, wrapped it in 2" of high density foam and duck tape, and suspended it from zip ties from the steel frame and it's STILLL very audible inside and outside the van. I'm investing in the silent pump made by James Browning-Smith!
You can start them on the pump then switch to gravity feed if you can measure the flow well enough. No pump required.
Ottimo lavoro!
Good job, from Italy.
Great idea. I’m a retired Truck Driver and the last few years of driving they added diesel heaters. That clicking fuel pump was terrible. I’d wear ear plugs every night. Other drivers said they got use to it and slept fine but I never did.
Thanks Bill,
Since this video I've change it all around a couple of times..!
I think ear plugs is still the only answer though...! 😂
The rubber bracket is a great idea, but I would also be tempted to insulate the area where the pump is situated with sound deadening material
You’re awesome . Very well made and extremely informative .
Hi Michael,
I appreciate that...
ATB< Steve
Thanks for your awesome English (I'm Italian) and for your instruction. I will adopt it when install the heater on my sailboat !
I have tried many many things to stop the tick tick , The best i have found is suspending the pump in some white PVC drain pipe filled with expanding foam then hang the pipe from 3 cable ties ,, I have got about 50% reduction in the low tick and 90% in the mid range Bumble bee sound
what about suspending it in mineraloil? such as used in computers. that will propably eliminate the ticking
What size pipe did you use ? double the size of the pump. or smaller ?
First time I saw a pump from the inside .
Excellent video, thank you 👍
Great job on your easily understood and informative product ion video
Great vid, thanks!
That is one heck of a difference! Thank you for the video! I guess it would be possible to build a sound dampening box around it. Sure it's a lot of work for a cheap device. But totally worth if the sound comes across as bothersome. I guess buying cheap sound proofing material for cars and clad a box is enough. But if you are going hardcore and want to eliminate ALL THE SOUND. make 2 boxes, air gap in between the boxes. (use rubber feet in all directions. Seal the boxes completely (no air should be able to travel). The fuel hose needs gaskets and sealant through every box it enters/exits. Mount the box with high grade industrial rubber bands to eliminate vibrations. I guarantee it will be dead silent. ;)
Good idea. Bit like double glazing
I suppose it all boils down to how much it bothers you really.
Once up to temperature and with the pump barely ticking you have concentrate to hear it even with minimal sound deadening.
I don’t run it during the night so no bother there.
ATB, Steve.
it makes a great metronome.
Good work! I also did pump hanging useing with spring. Main poin is DO NOT ATTACH THE PUMP ON YOUR CAR
Thankyou for your clear comprehensive videos. I am ready to fire mine install up ..
Your welcome Jacko,
ATB, Steve
Great video thanks
Another great tip.
That was very interesting, thanks.
Yes maybe some sound deadening material would be the final fix? Worth a try! Great video thanks
This is brilliant. Thanks mate!
Thanks Dan.
ATB< Steve
AWESOME! Thank You!
Great video and channel, Thank you for the informative video.
My chinese heater came today, was thinking about that clicking. Planning to use those insulation covers for hot water pipes, because until now i didnt now about those fancy jackets :)
Truck House Life does a really good install video of a webasto heater..
Total GENIUS!!! 😀
Wonder what would happen if pump was wrapped in noisemat used in cars that sticks on???great video!
As long as it didn't get too hot, it probably would work.
I wouldn't imagine it would get very hot at all. Especially when it's cold enough to need the heater and the cold fuel going through it will also provide some cooling.
The best solution I've found so far is to loop two medium sized plastic zip ties through that rubber ring you get with the pump, leaving them long and loose, and squeeze that back onto the pump. Then loop another zip tie through those two, again leaving it loose. Then add just one more that you cinch down onto a screw or hook that's mounted to a wall. Make sure the first two loops come out the top of the pump (the output). This holds it vertically.
My pump and heater are inside my bed, which is basically a large box with a hinged lid, so it's fully enclosed. I used to use bungees to mount the pump, but they didn't help. I could hear the thump, thump, thump when I put my head down on my pillow. With the zip ties I literally don't hear a thing! There's something about the loose coupling between the loops, or the plastic itself that doesn't transmit the thumping to by bed.
No sound-deadening jacket needed. The problem is not the sound that comes through the air, it's the solid connection to your vehicle that is the problem. (Assuming the pump is hidden away in some sort of box.)
Any photo of this by chance? Sounds brilliant - but I got a little lost. thanks!
Any chance of a photo?
@@sketchbookinc.6564 I have seen the solution; basically you can toss the mount and suspend the pump with HANGING (loose) zip ties. But when you use this method you must still maintain the 35 degree upslope angle of the pump. In summary, ditch the mount.
@@petesmith9472 Upslope on the chinese can be vertical, they took the instructions of the German models..Guy on youtube "Expert " goes into the fine details.. John Mck 47
I've suspended my pump via zip ties and, even in mid-air, the ticking produced by the metal cylinder in the pump is still very audible and annoying, both inside and outside the van. I also have it wrapped it in 2" of high density foam and duck tape! I keep reading about folks "silencing" their pump by this method, but I haven't experienced it in my experience. I plan to invest in the actual silent pump made by James Browning-Smith.
Thanks for that. Fitting one at the mo. Its lubricated like an injector pump with the diesel itself. Not sure about the union jack though.
Very good video especially when you showed the inside of pump. 👍 now I just wanna know how it works inside the combustion chamber
Hi Flicki,
I'm working on a combustion video at the moment...!!!
ATB, Steve
I like your fuel cell bracket lol
thanks for the tips lad
I hang mine on a wrist loop sized cable tie to the bracket and it really quiets it down. The rubber was transmitting too much thudding sound though it helps a bit. Cable ties are the go and adjustable for the quietest effect.
The pulsing noise is also transmitted up the hard plastic fuel line. I wrapped my pump in a towel, further wrapped in sound deadening mat, then placed in a plastic box. I suspended the box and fuel lines with stretchy cords to ‘float’ everything in free air so that neither the fuel line or pump box touches and transmits vibrations to the body of my camper. Works like a charm, no noise whatsoever. Looking to find a softer, more flexible chemical resistant fuel line though for future installs.
Good job!

Greetings from Jakarta
Absolutely top job enjoyed every minute of that I've got one on the way so we'll be making my way through your videos subscribed
Thank you 👍
I 3d printed a mount/cover out of flexible TPU, I worked really well. I cant hear it at all through the thin wall of my Boler. Mostly it is how/where you mount it though. The physical vibration if mounted wrong can make the whole trailer a giant drum.
Perhaps you can also attach rubber mold grommets to the screws to minimize the pulse vibration.
Thanks 👍
Can use pipe insulation thats round and goes around completely but good idea sir and strap it at the end on each side
Thank you ! I too tried various ways to isolate the "tic" completely sealing it in a box 1" thick Ceder. Nope, sound transfers out and down the fuel line. Yes, I am using nylon line, I suspended the pump in box. The difference? Went from a tic, to a thump. Far worse than before, so, I simply suspended it with small Bungie cords in a semi open area. Anywhere the fuel line touched anything, I insulated with micro fiber rags. This did not eliminate the tic, however, it now is so subtle it's barely noticeable. I am super Anal about noise, hate it ! So, if it works for me, should be fine for you. Just know, the sound will transfer through the fuel line no matter how well you seal the pump . Or, move pump as far away from living area as possible. Mine is in a Van build so...Love the heater though 🤟🤟
Hi Alan.
I'll give that a try, thank you 👍
I appreciate the cut away!
Thanks for your video. Yes the click, click, clicking can be very irritating, particularly at night. I’ve even contemplated encasing it with expansion foam but nervous about having to replace it. I’ll give you ideas a go.
Hi Bevan,
Yes, it bugs a lot of people...
Worth experimenting I suppose....
ATB, Steve
I’m not sure how effective expanding foam would be because it has so little mass. If I was gonna try it I’d;
1. make a small plywood box that can house the pump.
2. cut it in half, the box, not the pump😉
3. Offer up the pump and tubes and mark where they pass out through the box.
4. Use a rat tail file to make slots for the tubes to pass through.
5. Cut 2 pieces of cling film, Saran wrap big enough to cover each half of the box opening and wrap around and be taped in place along 3 sides.
6. Lift up the unsecured edge of the cling film and squirt a small amount of foam in to both parts of the box and quickly assemble around the pump clamping the 2 halves of the box together.
Once the foam has hardened separate the 2 halves, peel of the cling film and you’ll be able to reassemble with what ever method that suits you. I’d use zip ties and also hang it from a couple of others so that no internal vibration can pass into the chassis or bulkhead your fitting it to. I’m betting the box will absorb more sound than the foam so id be tempted to try it without first. Also wrapping either the inside or outside (or both) of the box in sound deadening mat would help.
Thanks 🙏🏻
Thanks !
I have 2 of my pumps inside pieces of lead waste pipe, and have them suspended like yours, drops the noise a fair bit.
Also going to try using same pipe to make a better muffler soon (1 meter length worked great on my old 5kw chinese diesel genny)
Another system in my house bus, has a quieter (type E) pump, which i wrapped with exhaust wrap, which makes it almost inaudible inside, and exhaust improved a lot with entire length also being tightly double wrapped, including standard muffler.(soaking well in water before using, makes it so much easier to use), and prevents any risk of it starting a grass fire.
good vid, love it, first time i have seen the inside of the pump :)
Thank you
Glad you enjoyed 👍
yes very helpfull
Well done
I made sure there were pigtails of fuel hose either side of the pump so sound was less likely to be transmitted by the hose, I then used one of those pink covers and experimented with cylindrical rubber mounts that I machined down to make them more compliant, I mounted the spin off fuel filter and a webasto style fuel damper and the pump all below the floor of my van so that all the noise was outside. We can still hear the pump but it sounds like the ticking of a distant clock. That worked for me, but I doubt the noise can be made inaudible.👍
Thanls bud
The solution does not lie with a cushioning pad. 95% of the noise comes through the fuel line. Notice the movement of that small air bubble in the filter. The solution is to use a 10-inch piece of soft and really flexible, slightly curved fuel line on either end of the pump. Not that stiff and hard rubber that is commonly used. In my case it reduced the noise by at least 95%. A shocking result.
Great video by the way.
I was thinking the same thing
Is the soft flexible fuel line readily available at any automotive supply company? And I’m assuming that it needs to be the same ID as the materials supplied in the kit. Correct?
.
It's normal that the stiff PVC hose moves with the impulse from the pump, that's how the fuel is pumped on. The heater relies on that impulse. Some of the heater kits came with flexible silicone hoses, they didn't work that good. For my kit I decided to get one with the stiff white hose, just to be sure.
The looped cable ties works really great, had many positive reactions after recommending it!
:-D
THANK YOU I am just starting van life . solo female van life
I sing blues songs to the tick on low and rock n roll songs when the tempo increases 🤣
😂😂😂👍
good vid thanks
Making sure all air is purged out of the pump helped mine immensely, the fuel cushions the pistons blow, any air will allow the piston to hit the body of the pump harder.
I’ve not worried much about the clicking sound. When I wake up and hear the clicking sound I know the heater is working and I can go back to sleep .
Thanks for that. To say that the pump is unlubricated is not quite right, since it is self-lubricated by the diesel.
Hi Dirk
Yes, I know, a lot people have mentioned that.
I should of added, “not externally lubricated by a separate oil feed”.
Obviously the clue is in the name: Diesel Oil.😂🤣😂
ATB, Steve
I just received my Diesel Heater today. I got the one that comes in a metal case already put together, and I bet it’s going to TIC fairly loudly. The Solution I plan on using is Pumping Up The Volume of my 🔊🔊🔊🔊🔊🔊 STEREO SYSTEM 🔊🔊🔊🔊🔊🔊 🤣😂🤣😂🤣🤪🤪
I did it very simple to ours. Use a car radiator hose. I am into the automotive sector. So i could get one what perfectly fits around the pump. Only the connector part could not fit. Put at the other site whats is free another thick rubber hose into the bigger one so that a lot of the pump is covered with rubber. Big difference according old situation. You can hear it ofcourse but a huge difference than before and at a very comfy level. Think simpel…..
I know exactly what you mean, I have the same system and was considering addressing the same issue.
I'll probably do the same and may even encase the pump in a small plastic box, packed with some form of sound deadening material...
Nice job there though.
You can buy a special designed pump housing, temperature and noise covering, from china.
I'm going to check it out in the winter
@@wildcatcortex If it silences the 'clicking', that'll be great.
You'll have to tell us about the progress.
@@PreparednessVeteran Just waiting for delivery ... china stuff you know ...
The pump should be at a 45 degree angle. They also sell covers for the pumps that muffle the sound substantially for about $8 from china. It also has to be floating, even with that rubber it will still push vibrations to the other surface.
Hi Fedor,
When the pump pulses it creates cavitation within the pump body, which is tiny air bubbles.
If the pump is at an angle these air bubbles will become trapped causing two problems:
wear within the pump & incorrect fuel dosage, leading to a lean fuel burn and incorrect combustion.
With the pump at 90degs any cavitation will be completely avoided.
Instructions say 45dges, which is the lowest angle you can have them I would think, before it becomes a real problem.
I am experimenting with that type of foam cover as well.
A case of trial & error with different hanging methods also.
ATB< Steve
@@TheWrinklyNomads Cavitation is not a problem unless it's horizontal. At 45 degrees the pump won't go dry when the line goes empty. There will be some fuel left in the corner of the pump. If it's at 90 degrees, or vertical, fuel can drain out completely and the pump will eventually fail prematurely from repeated metal on metal contact. The other reason may be for debris control, so any particles would fall to the corner instead of blocking the inlet. I'm sure there are other reasons but I can't remember at the moment. There's no reason to mount it vertically, there are multiple reasons to mount it at 45 deg. Do whatever you feel is best.
Thank you for taking the time to cut one open! I am looking for a controller to run this style of pump independently from a heater. Can you help point me the right direction?
Yo - PG. thanks (from Texas). Did you have any over heating using that pad ?
Hi Thanks for taking the time to make this video I was wondering if you have a like to the Sound reading Jacket i can seem to find any think out there
I got it for eBay, but unfortunately the company doesn’t seem to be on there any more🤷♂️
Submerge the pump in the fuel its pumping, diesel is hard to light, sparks won't ignite it unless its mostly vapourised, and a lot of automotive manufacturers already do it in unleaded high octane fuel systems to deaden the noise of high pressure fuel pumps. Make a good seal on the electric plug or change the plug so it is 2 individual wires and seal them completely separate until out of the fuel of your worried about it causing grief.
Grande bravissimo
Thank you Roberto.
I’ve seen in other vids that the pump should be mounted diagonally with the outlet at the high end.
Have you thought of sound detaining vehicle insulation attached to the walls of the vehicle. The come with peel & stick panels. It add temperature & sound insulation. Manufacturers use this to reduce noise in the car’s engine firewall & flooring areas.
Can't someone design a pump that has Teflon O rings or some synthetic pump material to make it quieter. I bought a self contained diesel heater recently but haven't tried it yet since we are still having a hot summer here in California. Can't wait to try it out. I'll try wrapping the pump first. They've dropped significantly in prices as mine was only $89 US dollars.
Thanks for rhe video. I was lloking for info how to make it quiter. Maybe its worth changeing to some quiter pump ? Or the diesel consumption and power may change ?
Iv moved the pump to the underside of the vehicle. Wrapped it and hanging it using rc silicone pipe (very soft) and replaced all the fuel lines with rc silicone pipe to stop the sound traveling to the heater or fuel tank and I literal can not hear the ticking inside the vehicle
Shouldn’t the pump get a slight lubrication from the diesel as there is a slight amount of oil I diesel. Love the videos
Good video!
Greetings from germany. Thank you for the good video. I was thinking of doing something similar for a carbureted gasoline pump. One question: is there a risk that the pump will overheat? ...risk of fire
Hi,
I did think of that as well.....
But with diesel there's very little chance.
My only real worry was vibration and working loose.
So far so good though..!
ATB, Steve
If that rubber exhaust mount is made of a hardish rubber (I'm only assuming because those rubber mounts are usually solidly designed to hold the weight of an exhaust) then I reckon you won't have really done much to deaden the sound. It will transmit through the hard rubber, into the bracket and then vibrate through the van's surfaces. You really need to find as light a contact between the pump and the mount as possible so I think other less dense materials would have been better. It would have been interesting to hear the result if you had just held the pump in your fingers for the purposes of the exercise and see if there was a sound difference. But thanks for the great video and has me thinking about my own situation in more depth.
yes, I know Reg, maybe should have experimented with different materials.
Some use a couple of tie wraps an just hang the pump from them.
For now it's fine, especially in tick over.
Why not put sound deafening foam in the whole space that the pump located? That hollow box is an amplifier(aka speaker box) for that clicking sound!
I did that and it realy helps a lot
I found the noise is not so much the pump alone but , like the OP , the pump/van body interface ( so to speak )
I hung mine off an exhaust strap ( impregnated cloth type ) similar to in the video but one that is about 4" long,,, I mounted it UNDER the floor too
With the pump external to the hab area and isolated you have to listen REAL hard to hear it at all :-)
Been uming and arring about getting one of these. Problem? Where to put it? I’ve got a Adria Twin on the Fiat Ducato. So that’s a PCV.
The only obvious place would be under the drivers seat, using fuel from the vehicle fuel tank.
How much “headroom” does the burner body require. I reckon I’ve got about 20cm.
Any thoughts? Be appreciated.
I haven't tried it, but I would imagine if you were to put a 3" plastic drain pipe over the pump, about 6" longer than the pump, fill the pipe with silicone, making sure there are no cavities, then cut the pipe along the length and remove, then wrap the fuel pipes either end as much as possible with some felt or old carpet, then suspend the pump vertically, on a zip tie so that it hangs in mid air, there should not be much sound coming out of it then. I have just bought a heater, and that's what I am going to try, and hope for the best. Paul UK.
Hi Paul,
Yes, people have also suggested similar to that in the comments.
On tickover the pump is very quiet.
I've just got used to the little tick now and it doesn't bother me...!!!!
Great idea. It's a shame that there isn't a different style of pump that could be used that's quieter
Look on the forestry forest you tube sight, a follow made one that is quiet, 3 month ago now maybe. Or when on sight ask him about it. Wish you the best.
The only true way mate. Is to some how make a type of silencer.. A bit like a pistol or rifle type silencer.. It must surround the whole of that annoying pump.. That's what I plan to try and make.. When my Diesel heater arrives.. Cheers for the vid though mate.. It might give me a few ideas.. Take care.
I've heard tell that mounting it at a 45-degree angle quiets it down quite a bit. I think auto sound mat around it would help as well. That ticking would get bothersome quickly at night. Thanks for opening one up. Interesting to see how they are made.
Can cover the walls of the cavity where the pump is with sound absorbing foam, same kind they use in recording studios
I fitted mine in front bulkhead of my caravan, ive hung it at an angle on cable ties and can hardly hear it now, also bought the pink rubber jacket for the pump but not got round to fitting it yet
Hi Ted,
Yes, I've heard those jackets are quite good, might try one myself.

Hi
Thankyou for your informative vlogs.
I have to replace my fuel filter. The original type are very expensive and I was wondering if a in line automotive filter would be suitable? Thanks in advance.
All the best

Hi Kevin.
I haven't found them too badly priced..?
The fuel filters are quite good value here:
