Hello, I've had problems with starting and have to prime to start. I rebuilt filter head twice with the oring kit then over Thanksgiving weekend replaced filter head with a new one . Still have to prime to start. Not every time but almost. I do not have a lift pump so if I install lift pump will that solve problem? thanks in advance for any advice. I,ve had truck for one year and have not been able to fix this and would like to get it resolved. Kinda bad to have the work buds in truck to get some lunch and have to get out and prime the fuel. Truck has 208,000 miles.
