After replacing the gear pump i noticed that i wasn't priming the system enough to get all the air out when i was changing out the fuel filters.... so now i do 5 or 6 primes just to make sure all air is out and then i check if their are big bubbles coming out of the IFSM with a compucheck.

what port on a pump you use to check for bubbles? i see there is 3 of them. could i buy this fitting in any store or it is from cummins only? thank you
