Does anyone know about how much more HP this adds?

Outstanding! Didn’t know you could get to it from the top! Doing it tomorrow!

Its the same allen screw. Just from different access. How sensitive is that screw? Should i turn it one millimeter or one turn. I have read that in rotary pumps turning up the fuel will also advance the timing at the same time. So overdoing it is bad.

Mine don’t have that in it!

My internals are not spinning when I turn the pump and it’s not pumping fuel

Is this the same process for a DB4 pump? Im needing more fuel out of my DB4 badly!

Hi @Eric K, thanks for a very clear explanation. Can you possibly tell me what makes the engine go to full revs even though the throttle cable is disconnected. There was a video here somewhere that tried to explain that if the top cover you have taken off was placed incorrectly it would just rev full ball. I had my pump rebuilt but now that I have re installed it I just keep getting this problem. I have the same IP and any help on this would be appreciated. 🤔

Wow! I have been looking for months to find someone with a 6.5L diesel that matches what I see in our 6.5L diesel “pusher”… its a 95 and its in a FLEETWOOD FLAIR 32 foot Class A RV. I have wanted know how to adjust the fuel, as well as how to boost the turbo (since ours has a Mechanical wastegate actuator, instead of one with a vacuum pump… it came stock that way). Can you provide any info towards that endeavor? Your a good man for sharing my friend! Thank you!

You can do it from the side on a ford

How do you know when it needs turning up

Bonjour Mr vous avez un tuto pour le démontage de la pompe ?cordialement Gilles de France 😉

Very nice videos.

Just get to the point already 🙄 good video though

Great that you share your knowledge for all to use!

Thank you so much! Best video detailing how to do this by far. I didn’t know about the side inspection port, thank you for pointing it out. Luckily I’m also replacing the intake on my 6.2 to a J-Code one so I think I’ll be able to kill 2 birds with one stone on this! Thanks for the tips on how to take it apart as well.

What size allen wrench did you use?

Hell yeah, man. Thank you. Clear, concise, helpful video.

I have a non turbo 6.2 in my 1985 1028 4wd dually its all stock from the military, how many turns clock wise do you recommend?

I need that pin and spring that is in the end where the timing gear goes I think it pushes on timing cover to push on end of pump if you have extra one will you please respond with info so I can buy from you. I thought mine was stuck in pump but must have jumped out after I removed pump I know it was in there but went to pick up pump and gone. Thank you

Check engine light is on... :)

Cool thanks

Thx you mister K!! 😉

"impossible to work on" a hummer. LOL. Try turning the fuel screw on an IDI van.

Thank you, this showed everything clearly in great detail, the issue I have, I can not get the fuel screw to turn.... I put a wristpin from a briggs on the allen and put a lineup bar in that, turned till i thought the wrench would snap and stopped, i did it with a wrench too, even in the opposit direciton, nothin. Edit: Oh I never had fuel when i took the triangle plate off the side.. I am runnin a 6.9 idi on a bus. It has never had an issue starting and even when i bumped it fuel never came out.

Great explanation Eric Big Thanks for your video

Does this increase flow rate, pressure or both?

Thanks for taking the time to make that Video Eric ! Liked/Subscribed !

Hey I have a 6.2 with the 6.5 trubo stuff I turned my pump up 1/8th from stock and was told I can go one 1/8th more with the turbo? My motor came out of a 90ds 3/4 ton exstedded cab

Can this adjustment be done on the computerized models also? Thanks

Best video available right now.

I finally made the adjustment to the pump and what a difference, 1985 gmc p-30 non turbo step van with 6-5 i set it between the non turbo and turbo setting ,, between 2 and 3 o'clock and I hit the hill and I can barely see a black mist coming out of the pipes, and it picked up a lot more power and torque hell ya,, so dont think about it just do it..

is there only one screw to adjust

looks you open and closed a lot times that type of diesel pump you are good on it!! great vedeo mate cheers from norway

Thanks for posting Eric. Your video was helpful.

that IS pretty awesome!

Where is the rest of it

Whats the point of this

Someone is wrong about hummer h1 mpg it's 8 on city and 10 on Highway using 6.5 diesel and it's 32 gallons fuel tank

107 false SUVs drivers do not like this video

Wow, you are in contention for world's biggest douche

i Love the Hummer!!! full body shoot of that!

Money makes shit happen man

@jcaled24 no i was trying say what do u know about paying tax..

whos bmw was that?

@kamigawa125 u mean your food stamp..

Good Job, Guys from the Army. That's how you spend our tax money. Keep it up.

@528jkl I'm not sure you had to classify an entire country based on one person. I guess all the people in the country you are from a narrow minded like you?

i dont get how testing the front brush guard on a bmw proves much.

WTF????

this isn´t french parking, right?
