History, 1990 F350, 7.3. Bought as project truck. Was horribly maintained by previous owner. Had fuel leaks everywhere, replaced return line injector o-rings, fixed filter housing, using one piece fuel filter. New lift pump. Not a drop of fuel now. Problem, I’m having is seems like pump is losing its prime. Once started it runs good until next morning, it is extremely hard to start. I was thinking, its sucking in air between tank and pump so I temporarily run one fuel line hose directly from one tank to the pump. It runs good, but next day I’m back to hard starting. BTW, it has a new starter, two very good batteries, it does turn over fast during starting. Do you think I have a problem with my injector pump? Could lift pump be sucking in air? Any help would be appreciated.
