i read through about 50 fuel pressure posts and i know that everyone
sees a jump in fuel pressure with the install of a wahlbro 255.
but i fixed that when i had my stock fpr on by drilling a small hole,
then i got an aem fpr and installed it. got it down to about 56 or so with the screw all the way out.

well know all of a sudden when i started mycar up one day the fuel pressure was at 76. so i put the stock drilled out fpr the pressure was 82!! Some of these posts people say that you might have a blocked return line but i can't see 50 people having a blocked return line.

I checked anywayz and it's clear. Not bent or dented in. Does the walhbro 255 have a return on the pump itself. i know its not called a return but you know, a pressure return incase the flow line gets backed up it'll loop right at the pump and maybe it went bad. anywayz i guess i try my stock pump?

That's what the FPR is for. Turn down the pressure.

 

lol good info ! wTF? anywayz so i took the regulator off and ran it into a bucket and the fuel pressure was 92!!!!!!!! WTF. Is the 2 way valve the tank vent?i looked at a diagram and that runs back to the evap canister. i unplugged that and it was still high so i guess its not a plugged up can?! i've blown through the return line. but like i said with the return line going straight into a bucket it reads 92.

bump. Did you put that other FPR on yet?

 

yeah and it works with the stock fuel pump but then i throw my wahlbro back on there and it goes back to 80psi and when i adjust it down it stalls around 70psi.?????????????
