Fuel pressure not adjusting...??? Good morning gentlemen. I have a slight problem with my new fuel system which leads me to a few questions. (LS1 Swapped into a 63 nova)
1) Why wont my fuel pressure adjust?
2) I have a boost referenced FPR and no turbo/sc. Do I need to plug this into vacuum?
Here is my setup. Aeromotive intank pump, 1/2" feed and return hard lines, braided lines to and from Nasty Fuel Rails. I run the fuel feed line to the drivers side rail first, it crosses over to the passenger side rail, exits passenger side, goes to the regulator, and then returns to the tank.
Right now the needle on my FP gauge (mounted on the reg.) is right at about 50# and I cannot adjust any higher. The car runs and drives alright, no hesitation, stumbling etc, but it is definitely not right if the pressure cannot adjust.
Thoughts, anything to check, etc? Thank you for your help.
