well now at like 1300-1500 rpm my truck surges, and i thought it was the fuel filter, so i changed it, but it didnt really make it any better, and i want to adjust my fuel pressure, i have a gade but i cant find a shrader valve anywhere, napa and shucks both say they cant get it, any one have any ideas, i have the tool, but no fitting

You dont have a schraeder valve on your 02...............


99+ FPR shim instructions.

It wasnt a question, it was a statement.


Read the article I linked.

hmm ya i kinda thought that, but wasnt sure, thanks, well that artical shows that his gage has the right fitting, but mine doesnt, so i was tryen to see where to get one

The fitting is on the back side of the fuel filter canister on the drivers side of it. I takes a Boss o-Ring style fitting and I think it is a 6 but dont qoute me on that. Then you just need a Pressure gauge that can be hooked to that type of fitting some way. Preferably Liquid filled gauge. If you have a Parker Hose store around you they can fix you up.

another option for reading fuel pressure is remove the plug in the pass side front of the head, put a 45 degree street elboe in there, and a schrader vale adaptor in. then leave it there for future use, this is what I do on customers trucks when needed.

but i cant find a shradervalve anywhere, thats my problem, and now the pulsating is getting worse

 

[Heywood Jablowme]

Most big parts chains should have them in the Air compressor/fittings section

ok, i found a fitting and checked my pressure, it was about 60, i put a bb in, and it went to 100, i didnt have enough time to remove the bb so its still in there, ill take it out soon tho, but i unloaded my evolution and it stoped surgging around 1500rpm, and the hight the level 1-2-3 the whorse the surging, but i put it back to stock and it stoped, what does it sound like the problem could be?

 

[Mike]

Dont run your fuel pressure at 100 psi, your pump die a quick but ugly death.

 

[scheid6996]

i didnt have time to change it, ill change it back as soon as i can, i had to go to work, i plab on changing it today when i wake up, im working night shifts now, it sucks

 

[scheid6996]

ok so got it turned back down to 70 psi now, but i still cant figure out why the evolution whould make it pulsate around 1500
