As i said, i'm new here, so if this is in the wrong section, don't kill me . Not sure if this is an electrical problem or what, but basically my Fuel pressure is not constant. I have an upgrade fuel pump which is hard wired to the battery and is running off a relay. Also, changed out my stock FPR to a Aeromotive 1:1 FPR. When the car is relatively cold, FP is fine, then as the car gets hotter and hotter, the FP start to creep down. It usually drops like 4psi. Does anyone have any ideas why this is happening ? I'm pulling out my hair !!!!!! AAARRRGGGHH !!!!! Btw, the battery and alternator is fine too. HELP HELP HELP....PLEASE ?
