A fuel pin and a 3200 rpm governor spring will wake your truck up significantly. They are a great "bang for the buck" combo! See my video here for more details on the governor spring: czcams.com/video/8zejOa9lun8/video.html
Awesome videos! When you add the fuel pin and governor spring, how does it affect your mpg? Thanks for the videos
I bought a used ve. Pump for my dads 93. It had a fuel pin and a 3200 gev spring. But when i fired it up it ran away any idea what would cause that ?
@@phonypony5.0 back the full power screw out until it won't start, then turn the full power screw in one turn at a time seeing if it will start. Get it to where it will start but doesn't run away. Make sense?
@@decentgarage yeah it does ...just have to sneak up on the adjustment cool thanks btw found your vid from LOUD & Proud 1st gen vid with the fuel pin ..great vids keep it up man !
@@phonypony5.0 thanks!
Hi Tim, i watched your video a couple of times and took out the odd original pin and replaced it with the pin you recommended,it was really easy to do. i took it for a drive after and it really does increase the performance. i'm going to try the spring tomorrow, thanks for the video
Awesome! Let me know if you have any questions with the gov spring. Just take your time, it's not that bad to do.
Thanks Tim as always.
Glad to help
Well done.
Thanks!
This is something im definitely doing on my Cummins swapped c30
Definitely do this and definitely get The Hungry Diesel fuel pin. It truly is the best pin out there.
Im trying to order one and it says governor spring required but i didnt see you change that in the video unless i missed it. Did you change it or left the stock one?
@@eulaliolopezjr go to the my other videos and the one right before this one is how to do the governor spring. The gov spring is only 20 bucks and is a huge upgrade so definitely do that too
@@decentgarage ill do that thanks
You really should invest in a set of Allen sockets, NAPA sells a good kit relatively inexpensively.
Luckily since this video I've gotten some 👍
well my top hat snapped and now i got junk great upgrade
I am assuming the fuel pin you installed is something equal to a 40 hp gain...if that's true do you have any concerns about stressing the trans? I have a stock 92 and a 40 hp fuel pin in the glove box waiting to be installed. I'm just looking for a little more hp to help with climbing hills pulling my 5th wheel...it could use just a little help pulling hills but my concern is burning up the automatic trans. From the background in your videos you have some really big big hills to get over...any issues with increase hp effecting your auto trans? Great videos BTW...very straight forward, great content and very well delivered...I watched several big youtube channels try to explain fusible link by pass...never once did they actually show the fusible link, or show the process for by passing, they just talked about it. Yours however, was detailed and comprehensive....keep up the good work.
You will be totally fine with the fuel pin. I would also recommend a governor spring. I lived in a Alaska for a few years with this truck and pulled a 5th wheel all over the state with my stock auto trans and didn't have any issues. Just don't pull hills in OD and monitor your trans temps and you'll be fine. I'd also recommend the basic band adjustments on the trans.
Hey man, did you ever make the smoke screw/star wheel video?
I didn't, my preference is to leave the smoke screw and bottom it the start wheel but then bring it up 2 turns. I may dig in to modifying it more later this year.
Great video.... question.... does changing the fuel pin and governor spring (3200) affect fuel consumption or reliability? My 1992 W250 5 speed is bone stock and I am not sure I want to modify my truck yet. Thanks in advance.
Making these changes will only improve fuel economy. It improves the fueling efficiency of the injection pump. Now, it does make the truck feel more peppy so if you don't have good self-control with your right foot fuel efficiency may suffer haha
Another great video. I got the THD fuel pin and 3200 governor spring as well and just installed them in my '93, which is otherwise completely stock. I did not turn the fuel screw in when installing these. The power improvement is really great - exactly what I was hoping for to get me up the hills a little faster when towing. The problem is at high rpms it now dumps quite a bit of black smoke. The rest of the rpm band is good - very little smoke if any. But when I get it revved up pretty high in 4th gear, which is the gear I'll be in on longer, steeper hills, that smoke is really billowing. Any ideas on how to cut down on that? My thoughts are, (1), increase preload on the starwheel spring or, (2), back out the max fuel screw a little. What do you think?
Definitely adjust the starwheel first. Rotate it counter clockwise which raises it up and increases pressure on the diaphragm. My got to starting setting for the star wheel is to bottom it out and then back it out 2 full rotations.
@@decentgarage Thanks Tim, I'll give that a try!
@@decentgarage Ok, I turned the starwheel up one turn from stock (two turns up from being bottomed out), and the high-rpm smoke was gone. Trouble is, so was my low-end power. So I kept turning it back down toward the stock position a little at a time, and now I'm at 1/8th of a turn up from stock and it's pretty good. Not quite as much low-end power as I was getting with it in the stock position, but I'm not getting any of that high-rpm smoke either. I am getting a puff of black smoke in the mid-rpm range, but it's short-lived. And after watching a video from my rear-facing dashcam from a while ago, apparently it had been doing that before I ever messed with the pump anyway. I guess I just never noticed it before. Next, I'm going to turn the starwheel back to the stock setting and turn the max fuel screw back a little to see what that does. I'll come back to report results. Might be a few days - too much rain today.
So I backed the fuel screw out about a quarter to half a turn and put the starwheel back to the stock position, and knew when it started up that that was never going to work. Completely gutless. So I turned the fuel screw in to just about 1/8th of a turn in from stock, put the starwheel to 1/8th of a turn counterclockwise from stock and turned the smoke screw in 1-1/2 turns from the point where it's flush with the cap and it's running great now. No smoke either. Also installed the manual shutoff cable and brass-tipped FSS plunger. Next projects - replace window scrapers, check backup light switch and troubleshoot lack of message center lights.
I recently got a industrial injection fuel pin and spring, and I was wondering if I tuned it like this one in the video if it would blow unburnt diesel more or less
It should go in just like this pin 👍
Any tips / tricks to get the four screws holding down the top of the fuel pin cover? I’ve got a good sized flat head but screws prefer to “strip” vice turn. Thank you.
Yeah, get yourself a manual impact driver. A gentle tap from a hammer with rotate the bit while also providing downward force and should break them loose.
@@decentgarage took a little doing, was concerned I would break something but thank you...screws came loose. Stock fuel pin was found and I’m waiting on THD fuel pin, 3200 spring and lift pump....thanks for your videos.
Is there a pin that will make it roll coal ? My 92 is not my daily so would like a little coal. Would just a pin change do this ? Or do other things need to be done ?
Thanks
He literally says in the video that he doesn’t want to install the “stage 5” fuel din that dumps a lot of heavy smoke .
Will a torn diaphragm cause the truck not to start?
Do you have the link to the combo? Thank you
He sales it as a combo for certain sales throughout the year. For now your just have to throw them both in the shopping cart and use the promo code 👍
Hey I just did a 3200 rpm gov spring and a fuel pin and now my truck idle went from 700 to 1000 what do I need to do to fix that
Back the idle screw off a little or change the indexing on the throttle lever
Hey I just pulled mine out today and there was this orange gunky substance that was covering the fuel pin. Any ideas on what it is?
I've had a few people ask that and I'm not sure. I would guess water got in somehow but I'm not sure how it found its way in.
@@decentgarage that makes sense. Thank you for your response
Hey Tim! old video, but maybe you'll still get the new comment. I have a VE pump, and its leaking a pretty good amount of fuel out of the little rubber breather tube at the back of the pump. have you encountered this? or maybe you know where I can find the part to fix that. thanks!
I haven't encountered that but I've heard it's an easy fix. The slide pin oring is probably bad and needs replaced 👍
@@decentgarage does your hungry diesel vendor have this?
@@jonmcginty1575 yes, he has anything youd need for a ve pump 👍
So I installed the pin but not the spring and it ran great when it spooled the turbo enough but it felt like it didint have any bottom end power any advice on what I can do to fix that?
Did you take out the little white plastic spacer?
Yup sure did still no luck would hardly make 10 pounds of boost as well I put the stock pin back in and it runs just fine but I’d like to be able to run my new pin
@@Ken-jt7ee interesting. Do you have the notch in the fuel pin pointed toward the front of the engine?
Yes sir followed you’re video step by step but still no lower end power. Could it be possible I need to adjust the pump to the pin?
@@Ken-jt7ee I've never heard of having to adjust anything after just adding a pin. You still have the spring around the pin?
Another thing to consider is changing out the spring riding the star-screw with a heavier one which slows boost influence on pin. Simply running the star-screw up, will also shorten the distance that the fuel pin will ride up the fuel pin. The heavier spring I run is a Bosch '1 464 618 705-001' Hopefully I got the correct number.
Dose that throttle position sensor go to the speedometer to make it work
No, it doesn't control the speedo at all
@@decentgarage I’ve been trying to figure out why my Speedo don’t work I’ve replaced both sensors and even tried a different speedo and still no work
@@Landon_Baker_productions have you replaced the gears in the vehicle speed sensor (vss)? In a 4wd it's on the driver side of the tcase, in a 2wd it's in the tail housing of the tranny.
@@decentgarage no I have not but will look into it, thank you sir
@@decentgarage can you make a tutorial vid on that kinda
I am using what I think is the hungry diesel pin but when I put it in the needle that rides on the pin isn’t coming back out of its hole I think it’s stuck how do I fix that because i got it to idle but it won’t take acceleration it just dies
That's called your slide pin. It's very common for the slide pin oring to dry out and cause the pin to stick. It's fairly easy to replace the oring. I don't have a video on that but if you Google it you'll find some how tos
@@decentgarage would this make it to where the truck will idle normal but won’t take acceleration or could that be something else
@@outdoorlifestyle9468 yes, if the slide pin doesnt move it can cause that.
i tried to start my truck after putting a new governor spring and fuel pin from the hungry diesel but the water in fuel light came on and it wont start what do i do?
Pull it apart and double check everything. I know you don't want to hear that but it is honestly the best way to proceed. Did you make sure to back the fuel screw out so the fulcrum lever didn't break?
@@decentgarage yes i did
@@decentgarage so what should i check for since my water in fuel light is on?
@@arielsima6650 did you recently change your fuel filter? Make sure your water in fuel sensor is working properly. Does the truck run fine?
@@decentgarage yes the truck was running perfectly fine before i changed this. how do i make sure the water in fuel sensor is working and where is it? and i think it might of had a new filter.
Does one have to change out both pin and spring or would it be acceptable to only change only the pin?
They do not have to be done together. Doing just the pin is fine
@@decentgarage Thanks! Will smoke increase?
@@rwk3547 not if you only do the pin
Anyone who has installed this pin and gov spring notice a different in MPG....?
I've heard that it can improve mpg but that sounds counter intuitive. Just looking for real world numbers
Does that code still work?
Yes it does
serious issues the power valve wont go in so the cover wont go back on mine was zero like yours my diaphram refused to go back in now the pumps junk even tried reassembling with stock power valve cover still wont seat ! theres a valve inside the pump that sticks on these you need to put a screwdriver inside and pop the valve back to get the diaphragm to pop back in and it will go pop
If I were to get an M&H stage 5 fuel pin, what other upgrades would I need so nothing breaks. I'm running a stock 1989 non intercooled. only thing done is the fuel pump is turned up a little. thanks! Love the channel!! i follow you on Instagram @t.revor_12v
Honestly an m&h stage is not good for much more than. Blowing black smoke. Get the THD pin or an m&h stage 3. I would also do a 3200 gov spring. Just those two mods will make a huge difference!
How much I have to roll the pin to roll coal?
You don’t want to roll coal
I don't cover that on this channel. Sorry.
@@tyashcraft9496 it’s something wrong with it?
@@nynoperales6521 fuel economy goes in the tank and you don’t maximize power
@@tyashcraft9496 ok thanks
as expensive as it is i love the trucks that can roll coal
Haha it is fun when fuel prices are half what they are now
Yeah, i won't be doing anymore 0-60 runs till probably 2024...
lol i dont blame ya there 😂 love your content man. 👍🏼
@@mentlegen8187 thanks!
No problem :D
I want to burn every ounce of diesel that I’m paying for 😂😂😂 I’m sure we’re all like that ... or we should
Agreed!
Who has 2 10mm wrenches?!
Jk
This guy!
Only "2"? 10 mm is the lifeblood of the 1st Gen
