it depends really on when your talking about, if your talking about idle then the FP is 35psi (18" vaccuum). But if your under boost it is gonna change accordingly...
take stock FPR rating 44psi then add 1psi of fuel pressure per 1psi of boost and thats what it should be at. (ex. fuel pressure should be around 49psi @ 5psi boost)
