Fuel Problem Cummins

Essentially it would run off of the lift pump feeding the high pressure pump until the lift pump would turn off at 30 seconds and than unit would die. Was hard starting also.

I put a brand new fuel pump on it actually man.. Old one actually had a bad camshaft in it so it wasn’t supplying enough pressure to the rail. Put a new pump in it. Then the injectors were giving me a hard time. I actually had them all rebuilt, just put them back in and everything looks good, just wondering why the fuel filter on the outside of the frame won’t stay full. It’s been super annoying.
