I’ve replaced the mechanical fuel pump on top of the raw water pump and the filter. I’ve also rebuilt the vapor tank and replaced the pump in it too. Fuel pressure tests at 37 psi which per my manual is good. I’ve also run all the old fuel I believe out of the tank and replaced it with fresh. The only part of the fuel system that I haven’t changed is the injectors. Unfortunately I’m still waiting on the parts to get here.mechanic said I needed a new fuel pump-replaced the water separator fuel filter -back to normal- wasn't getting more than 2000 rpm at full throttle
