Being a lake bum in Texas
Changed the fuel filter on the duramax last weekend and can't get the fuel system to stay primed.
Last time I changed the filter I removed the air bleed screw, turned the ignition on to cycle the lift pump and after a few seconds all is well. Tried that this time with no luck.
Tried pumping the little pump on the top of the filter mount for 10 minutes, no joy.
Little bit of air pressure to the fuel tank and a few minutes later the fuel starts flowing to the filter. Fire the truck up and run out of fuel within a few seconds.
Thinking a dead lift pump, or am I missing something?
