So I just took apart the FPR and the diafram has a little crack in it and is pissing fuel into the intake line. So I rebuilt the little F**KER and now I can't remember the correct proceedure for tunning it to the proper pressure. Could someone give me the heads up without a little step by step minus the flaming for being so ignorant.

Thanks luch

 

Need a gauge mounted on the pressure line or on the FPR itself if it has a port for a gauge. Turn the adjuster screw to tighten to bring up the pressure, loosen it to lower the pressure.

 

What pressure do I set it at and do I only need to set it at idle or is there some way to set WOT too.
P.S. I have a gauge right off the regulator. It's just been a while since I did thos and I'm drawing a blank. Thanks for the help

 

When you post in the Advanced Performance sub-forums, it is assumed that you know the basics of the motor

VQ30DE/K- 34psi @ idle and 43psi @ WOT
VQ35DE- 51.5psi constant (no vaccum applied)

Either way, the majority of people add AFPRs when they have a need for a higher pressure that the stocker can supply. With that said, shouldn't you know what pressure you need? Unless you just bought it for nothing?
