Which Fuel Pump Should I get?
So I am changing my injectors to 175cc/75 nozzles. Given the fact that I already have a driven diesel reg return, should I/do I need to replace my stock fuel pump? Previous tests i have done show under current conditions, up until WOT, the pressure stays at 65, while WOT drops to 58 (briefly) If so, which one? The AD 165 comes with a reg, but since I already have one, do I need one on the new pump or just the 150 without it? What should the fuel pressure be set to on the new pump if I need it?
