fuel pressure?

[tyron]

hi.
does anybody know how many psi a standard 328i fuel pump pushes?
any help would be appreciated.

Fuel pump output is measured in gallons or pounds per hour, not psi. Psi is determined by the fuel pressure regulator on the rail. stock fpr is 3.5 bar, or 51 psi. I don't know the gph spec on the pump.
