Fuel pressure
Posted: Fri Dec 03, 2021 4:38 pmHi guys. I'm wondering how many of you run a fuel pressure regulator on your street car; and if you do, is it a dead head or a return type.

Carter 4600 pump is rated at 100 gph, 4-8 psi, internally regulated. Most reliable of the external aftermarket pumps. And cheap. Work on the engine consuming 25 gph per 300 hp & allow a safety factor.
