That'* what I don't get. there is no fuel smell coming out of "the leak" only air. And I can do this over and over again in one sitting. One right after the other.
Another symptom I forgot. If I leave the fuel pressure gage connected to the rail after I turn off the car, within an hour or so, it drops from 40+psi to practically nothing.
I already replaced the fuel pump. the "check valve" is in the pump. I really didn't like how the pulsator connected the fuel line to the pump (on all other fuel pumps there is tubing with clamps on it) . It seemed not very secure. that'* the only connection where fuel could flow back and not be seen or smelled.
But for the fuel to recede (it can only be going back to the tank) or just lose pressure, we need a leak somewhere in the front end of the fuel system.
Fuel is a new area for me, and one I'm going to have to learn. How do I check the FPR?
