Iím thinking air in fuel system? OFV?
Will change fuel filter this week just to rule that out.
It isn't air in the system, why it was even suggested is beyond me. It isn't the OFV either with that much fuel pressure. Did you even take a peek at Joe G's writeup? https://www.cumminsforum.com/forum/9...m-writeup.html
While you are changing your fuel filter also take a look at the prefilter.
