I just replaced my lift pump and fuel filter. All my fittings seem good and I have no fuel leaks. However, I have to bleed my fuel system at the injector pump banjo and then crack my #1 injector while cranking to get the ol girl to start. Once it starts in the morning, it runs and starts good the rest of the day. Can air get in statically without fuel coming out when pressurized? Is this the end of my injector pump?

 

Yes, your pump can suck in air. Check any rubber connectors at the tank, etc. too.

 

Air penetrates the flexible hoses while they look brand new. The best way to avoid this happening is to change all the flexible fuel lines at least every second year in a hot climate. In cooler climates they can run as long as five years.
