Duramax Diesel 6.6L Won't Start No Fuel Have To Prime

[@mississippichris]

Mine wouldn't prime either. I took the priming pump off and replaced the O-ring. An O-ring from an assortment tray worked fine. 65 pumps later, I was primed and running.

I changed mine, did nothing. Same problem. The lower the fuel tank level, the harder the start. I also changed the fuel filter head.

My lbz just started loosing prime cant find the problem anywhere replaced the fuel filter with housing the sensor on the filter is not leaking. Replaced both lines going to the fuel filter housing. Cant see any leaks anywhere from the tank all the way to the fuel injectors its driving me nuts
