fuel pressure??
fuel pressure?? i have installed an inline walbro 255.
and my fuel pressure remained the same.
the truck runs better and the motor has more pick up.
so installing the new pump made a diffrence.
my fuel pressure remained the same, no change at all.
43 idol, 47 highway, 55 wot underboost.
what do i need to do to see the same pressure readings
as most of everybody else is seeing like.
50 at idol, 58 to 60 at highway and 67 to 68 underboost.
some have told me that for running 2 high pressure pumps
my numbers are way to low and should be much higher.

Are you using the stock FPR? If you are I would get a AFPR so you can set the psi to what ever you want. But with two high flowing pumps you should be building higher pressure with the stock FPR unless the diaphram is just shot in it.
