These videos are amazing. Hands down the best and most technical Subaru channel. Great video quality too.
Thanks man. Working on getting more out together. Stay tuned.
JackasstandJohnny 👏👏👏✌😁✌✌✌✌✌✌✌
a verry honest guy, simple set-up and budget friendly. keep it up goodluck for more project👍👍
Thanks. Just sharing the fun. Cheers!
You are a grate man with outstanding customer service and great service from the owner of the store and thank goodness for the service and the price for you to pick up the car
Nice job. I bought the Allsun tester specifically for the mode 4 function where you can just let the injector run for however long you want. I put my injectors in an ultrasonic bath with some cleaning fluid in it and let the injectors run for around 10 minutes straight. They came out nice and clean. Thanks!
+Baxrok2
Sweet. Thanks for sharing the experience! It really helps other people out there BIG time!
I was just thinking about getting one of those ultrasonic jewelry cleaners to use for injectors. Is that what you used? What type of cleaning fluid did you use?
I went ahead and bought one and used Homebrew seafoam as the solvent.
Good video, thanks for sharing your ideas
You can also pressurize the entire rail then close it so it doesn't build anymore pressure when you have it pulse and then measure the drop in pressure. A greater drop in pressure means the injector is cleaner than one with a lesser drop in pressure. This can be done on the car with the fuel pump. You just have to pull the fuel pump fuse after you pressurize the system.
Just want to know if the regulator are comes with tubings and fittings to connect the fuel rail?
I came here to learn about, and how to test, injectors - job done. Excellent video. Thanks.
👊 no problem. Stoked to have helped.
I used an old computer power supply and connected a moment switch to pulse the injectors. Worked great!
Nice 👌
What do guys do when the wife is away? Set up a garage in the kitchen of course haha
Pretty much. And don’t tell her what we clean in the kitchen sink!!! 🤣🤣🤣
I was thinking the same thing.
Wasn’t that your wife filming?? Lol
Hahah. No, my brother. She’s not into the whole creator thing…
The WARDEN came home early one day. I had the dishwasher running in the kitchen. You're running the dishwasher this time of day she asked? Was there enough dishes? We only ran it two days ago! You mean do I have the Holley Carburetor washer running? Busted!!! :P LOL
Damn this is cool. I'll be building one of these for sure. I'm going to just use a momentary button to... never mind that pulse device is sweet. I even have tiny 12v motorcycle batteries that I could mount on the back side.
+rc2300s2r That will be sweet. I love making custom tool or equipment - so much better than buying new!!!
Great apparatus. I will build one when I grind the caps away from junkyard injectors in the future to flow balance them.
👍
Great video, would it be possible to connect both injectors to the tester at the same time, perhaps in parallel ?, for side by side comparison
Thanks Bro my Mazda KLDE 2.5 v6 has Sidefeed injectors, gonna try your method to clean them.
Nice jig! Impressive!!👍
Freaken AWESOME set up.
+Nathan Cruz Thanks man. It’s a labor of LOVE for sure!!!
cool video, can you do a video on how you put together your apparatus? how does the hose that you pour the carb cleaner in connect at the bottom to the valve?
+Hector Vazquez I use a barb to pipe thread fitting. I'll put together an assembly video at some point in near future. Thanks man!
Keep making videos man! 👍🏼
+Lucas Davenport
Thank you very much! I'm LOVING this and plan on doing more and more! 👍👍
Hey so I'm trying to assemble this appiratis and can't find a 1/4 needle valve. They are all MIP Thread.
Thank you, that was an awesome video.
A sonicator does a very good job, fill your injectors with cleaner through a syringe (needle not required), put injectors in a glass jar filled with carb cleaner, put jar in sonicator and have at it for thirty minutes. Flush injectors with fresh cleaner and repeat the process, after a few flushes and sonications it comes out clean as a whistle. Then I'd put them on a rig similar to yours to determine flow rates and adjust spray patterns.
hey my side feed feel loose in the metal body crimp are they still good
Great review!
Great work! W
hat's your fuel pressure regulator hooked up to? on the other end?
Thank you for the detailed info
Np! 👊
Absolutely brilliant thank you
Awesome!
that’s the first time that I have ever heard the word “stoichiometric” used when describing air fuel ratio
nice video!
I love watching what different setups guys come up with for injector cleaning. Check out the Motion Pro setup. I found first hand that an ultrasonic cleaner and simple green works great, along with an injector pulser set to continuous for about 15 minutes. What I really want to see is a tank of liquid (simple green or whatever) that continuously recirculates under pressure thru an injector and returns back to the tank, going thru a filter in the process.
Carb cleaner does work wonders, but the small volume of liquid is insufficient. Honestly, once you watch an ultrasonic blow junk out of an injector, you'll be a hooked. But I really enjoyed watching your video, and seeing all the different ways guys come up with to clean their injectors. Can you outperform your first attempt, and come up with a recirculating tank setup?
I’m right there with you. Totally need to redo this for something like what you’re suggesting. Like it man, thanks!!! 🤙
Excellent Design Factor.
It's so simple ...thanks buddy
Np!
Hole eff! So you sir got a new subscriber
you must have won a few science fairs I checked mine by using a 9 volt battery alligator clips and a can of carb cleaner connected to the injector with gas line and duct tape it was enough to see that 5 would spray and one would not open at all. yours was much better than mine but I was proud of what I did.
I think I probably over engineered that sucker. Sounds like you knocked it out just as good! Cheers buddy!
can you make a video of replacing all vacuum lines on a sti engine EJ257 please
+Tony Guzman - Hear you and noted. I try to accommodate this for sure at some point.
Can't you run the injectors in parallel with the unit because it doesn't seem like the injectors draw too much power.
This is awesome!
👊
Bravo!
and well done!
Thanks! Cheers!
Could you just make a harness adapter to run the entire fuel rail? Like fire both injectors at the same time?
Muy bueno tu vídeo gracias por compartir
Can you tell me the Brand and model of the injector raíl, what car raíl?
how do you know which is the negative and positive on the fuel injector when connecting the battery >?
It didn’t matter - Just needs good 12v and good ground and it opened every time.
How exactly does the flow test work? I have a set of injectors that I'm unsure if they're OEM or DW's since as far as I can tell they look identical. How exactly do I determine the flow rate?
Hi. Great question!! Got to make some marks to see the volume in the clear tube, then hit the button to activate the injector and record the time you leave it on. Then, use the amount of time you activated the injector and the volume that passed through the injector to estimate the flow rate!
Awesome setup! I wonder if there is a way one could reverse clean injectors to get rid of any debris they might have inside.
Back flush - the most important part of the operation. A 9V battery will keep it open.
I bought one of those tester’s and for most high impedance injectors they are ok but around 12 ohm or lower it’s driver has too much resistance to trigger the coil
if I didn't have this type of set up for side feed fuel injectors ,would a back pressure cleaning be effective as well?
Yes. I have heard that back-pressure cleaning is a very good idea. I probably should try to do that as a matter of fact. Thanks for the comment bud!
I just use a fuel pump in a closed loop system. 1 gallon fuel can with the return and suction going into it and a walbro 255 extra pump I had and regulate it to 60psi since that’s what I run for fuel pressure. Then I flow match all used injectors and make matching sets.
Good set-up thanka
👍
Great video! Liking it a lot, im a skyline owner, i need to do this on my job list to hunt down a cold mirning misfire leaving me on 5 cylinder every morning to work. This is an ideal technique as its cost ne a fortune so far. skyline owners are generally a bit snooty over "unorthadox" techniques. Dont tell em i used to heavilly modify vauxhalls ffs.
lol. Nice man. Stoked it helped!! 😁😁😁
Fantastic job - ingenious setup!!
+burkilimo Sweet. Thanks
Does this work for direct injected turbo engines with a hpfp? Just asking because my hpfp at idle is between 500 and 600 psi.
No, probably not. Those need much higher pressure I think.
Top fed injectors also have screens in them.
Thanks for adding!! Good to call out for sure!
Do you know the voltage and amperage to the fuel injector? Using a car battery directly will fry the injector
Don’t know. But didn’t have any issues.
Dam just test the dam thing
Hahah. I know.
😂😂😂😂😂😂😂
I heard that, don't know why the heck he keeps rambling on and on? Wth? Just do it man... geez.
dude you are a genius...love this! very cost effective.
Genius!
My subaru forester 2008y (ej204) crank but won’t start, the problem is no fuel coming from the fuel injector, Please i need help
Thanks
Could be several things, I’d start with changing out the fuel filters. Good to do regardless. If that doesn’t help, I’d swap in a new injector to see if there is a clogged one.
I went out to my local Lowe’s hardware store. Spent about $54 just on hardware, tubing and pressure gauge. I already have the other tool. This was one of two videos I found on CZcams on how to clean side loading fuel injectors. I have a 1997 Nissan Quest . I will be making my version of your design. Thanks for the video man!
Awesome man! Glad it helped.
Nice. Arduino for injector control would be easy too and the minis are down to less than 5 bucks each if you buy a bag instead of 1 at a time.
Nice! Great idea man!
Definitely adds up to way more than $30. Just going by the title of this video. But like you said definitely way cheaper, just as efficient ways of doing this.
👍
That is pretty cool..
👍👍👍
Great video
Thanks! 👍
That’s a little complicated for me but very cool system
there are top feed fuel injectors that have screens..ie deka 80
I'm going to make one one of these for ford injectors.
Sweet man. Good luck. Easy little tool hack!
You need to if you haven't all ready seek a patent ! Good idea for sure !
+mrmagniffy Ha! Thanks man!
Wow, this is a cool diy invention. You should sell this blue prints or kits for us guys.
Haha, thanks buddy! Glad you enjoyed it!!!
Well done.
Thanks!!! 👍
Good job
Thanks
Awesome vid and set up! In my experience carb cleaner eats plastic. Maybe mix a cheap fuel system cleaner and isopropyl mix 🤔 . Subscribed
Yes. Good call! I found the hard way that carb cleaner also affects the rubber o rings if you leave it soaking too long. Made them expand and no longer seal properly.
Throttle body cleaner is less harsh and safe on Injectors
where’d you get the connections for your injectors?
Go to the Junk Yard get what you want for free...! Duuuh!
bad ass video
+Tony Guzman - Thanks man. This was the first one and I was learning a lot, BUT the apparatus works legit!
SubaruONLY No problem lol literally just watching one of your other videos 😂😂
when you hit the pulse, did you hold the button for the time or did the unit pulse the time? Thanks
Just need to hit the button once and it runs for the designated time. Cheers!!
@@SubaruONLY
Thanks.
My Honda engine is automatically cut off its working after heating since I started. Then after that I tried to start the engine but it didn't start. Then I removed the petrol injector and checked by starting the engine. But there was no fuel coming from the injector.Then what will be the problem.?please reply me
Sorry, I’ve literally never owned a single Honda. So I can offer much advice here.
@@SubaruONLYok thanks for the information
Np. 👊
Holy cow! This is some next level tweaker shit, I'm building one right now, this is gonna save my ass so much time, thank you!
How many pulses are enough to clean your average injectors?
+Arnold Ceasar
I typically run about ten cycles for each injector. But it really depends on when you stop seeing dirty fluid coming out. They clean up pretty quick! Thanks for taking a second to drop the question - Much appreciated!
Random question. Is it possible to upgrade from the aluminium inlet manifold to the plastic one? Is that a tough job?
Yes it’s possible and not too bad at all.
@@SubaruONLY do you think the plastic one is better?
I’m not familiar with those tbh. Better flow is what you want though.
But can it spit bars?
Great idea mate, so many issues with this setup tho. Subaru run closer to 3 bar (43psi) & you haven't timed the on periods so your unable to compare the injector flow rates correctly as a result.
Nice like that.
What/where is the indicated pos/neg on the fuel injector terminals.
I looked at the harness end, but think you’ll be fine trying either way to see which way works, or maybe both ways work.
@@SubaruONLY Yes of course!! look at the factory harness,,i tend to over think things,, great video keep up with the good work,, I'll get back with you when i build my injector cleaner..again i thank you.
Love to hear how it goes. Cheers! 👊
Yo can I come over? I need to test my injectors.
Nice
😁😁 wife wasn’t too happy to see that one our kitchen table... 🤣🤣
Very good device you should get a company to mass produce this item and sell them on ebay.
Excelente trabajo bien explicado muchísimas gracias 😊
😀👊
9:48 A cheap 0.01gram scale under the bottle, and you get exact measurement for the flow.
Wife comes home..."what's that smell in the kitchen"....guy smiles in carb cleaner
Haha, so true!!!
Ver y good
Thanks 👍
Could I flow test 4 diesel injectors at the same time with this set up?
Yep. For sure! 🤙🤙
I think Subaru only meant to say with this system you can but obviously you would need to add the other fuel rails or ports Because there’s only two ports.
If you think a gasoline port fuel injector, and a diesel common rail injector use the same drivers, connectors or operating pressures you should not be giving advice to people.
@@VTLIFE-so4dc I wasn't giving advice I was asking for advise!
@@toyota218921 Sorry if you misunderstood. SubaruONLY says "Yep. For sure!" But the real answer is no. Common rail diesel fuel systems utilize pressures up to 29000 psi/ 2000 bar or 200 MPa. Most port fuel injected gasoline systems run around 45-60 psi/3.1-4.1 bar/310-413 Kpa. So, common rail diesel injectors are peizoelectric, meaning the injector opens when current passes thru it because a crystal deforms, letting the needle in the injector open. It operates at 450 times the pressure of port fuel gasoline system, which uses a coil (electromagnet) to open the injector. The amount of current, voltage, and time it takes to perform the task varies greatly. The biggest takeaway to common rail diesel systems is CLEAN FUEL IS ESSENTIAL. DRY FUEL IS ESSENTIAL. ANY dirt or moisture is death to these systems. Good luck.
Definitely need to build me one of these. Quick question? A injector will not spray or pulse activate unless it has some sort of pressure to the injector correct?
Yep, uses the air pressure from a compressor. You can set it to about the same pressure your fuel system uses. Cheers! 🍻
Wait he has eyes behind those glasses haha
Professional injector cleaning pulses cleaner for 20,000 - 30,000 cycles.
Best to just add injector cleaner to your fuel tank on a regular basis. I use 5oz Lucas With ever fill up - purchase by the gallon and it's only $1 application.
Injector cleaner is snake oil. Unless you drive the car without stopping from full to empty, you will not benefit from the cleaner you shove in your gas tank.
Not talking about in tank injector cleaner ( which would actually be better than what's in this video ) . I'm talking about a professional fuel injector cleaning machine.
Thanks for the film. Also thanks, that you did not put any stupid noisy music under.
jajajajjjaajjajajaj I mean same jajajjajajj
43psi base in subarus btw!
Thanks!
you do know that allsun EM276 can run more than 1 injector at a time lol i just cleaned 6 and give em 30 mins in ultrasonic lol all at once
how did you set it up to clean 6 all at once?
Hey ....when?
When?
Latest video I see is a year old . What are you doing now Luke?
Go to 12:00 to see test
That’s a scientific contraption there buddy. 👍🏼
Good Job . You are using a pvc braided hose that melts with acetone ..carb cleaner .. Anyone that uses this system when it fails will be going to the hospital ..
"liquid pressure" lol
Hydraulic is the word you were looking for
Hahah. Thanks. True 😁
Nice set up but I don't like the idea of using carb cleaner to clean the injectors.
I hear ya! I think it does cause rubber seals to swell, which means use need to replace those after. Any suggestions for a better cleaner?
@@SubaruONLY fuel additives like berryman, Seafoam injector cleaner. Those are purpose for fuel parts.
👍👍
Thanks buddy!!!
@@SubaruONLY no problem
