| I actually just replaced the regulator a few weeks ago (it was leaking a little bit). My only thought is that the diaphragm on the pump is broken so all the pressure exits the system. I checked for rich conditions by pulling plugs to check for fouling in individual cylinders, all the plugs look good. The system SHOULD be holding pressure with the gauge hooked up between the fuel rail galley on top of the plenum and the fuel filter right?
