fuel pump transfer pressure
ive heard of it, cant find any pictures or instructions. Id like to increase internal transfer pump pressure but all i can find is there is refrences to a allen head in the fuel inlet. i looked, i took it out, i looked below it. I thought that was only on mechanical pumps but i keep seeing refrences to it on electronic pumps, Can anyone straighten me out here? Basically im in the market for more fuel/power and seem to have run into a dead end. I have a spare, brand new, pump i was thinking about taking apart and modifying then dropping off at a local pump shop for verification. But id rather not. Below are some pics of what i did yesterday, the brass fitting ended up being kind of leaky so it came back out for the stocker, need to order the right one. But i had all of that apart upgrading passages/hoses/fittings and i was unable to find a adjustment for internal pressure anywhere. :argh:

thanks, its just a spring and plug no adjustment.
:rocking: |
im an idiot. found it. :choochoo:

transfer pump pressure increased and a number 9 resistor is on its way to replace my number 3. will reset the ecu tonight and report back after my drive home. :choochoo:
|
Was it pretty easy? I already have #9 resistor but always was told that there wasn't a way to increase fuel @ the pump.

yea just gotta take the inlet nipple out and its hidden in the piece below it. if you dont look real hard it just looks like the sides of the inlet. Im not sure i can say it increased power much, seems to rattle a little more on start up and run a bit better when cold but again its hard to say.
