How to change fuel filter?
Can anyone tell me how to change the fuel filter on my Cummins ISC 8.3 engine. Difficulty, etc. Looks like it would be fairly easy.

My 8.3 ISC is self priming, no filling the filter with fuel required. Turn the key on for 30 seconds, two or three time, the electric fuel pump primes it and your ready to go.

Ditto and agreed. The Owners Manual is specific on not prefilling the fuel filters.
HOWEVER, now to add more confusion to the issue....
This past June at the GS Rally in Syracuse, NY, I attended the Spartan Chassis Seminar. The fellow giving the seminar (Mike) from Spartan, also worked for Cummins for several years. When the issue of fuel filter changing came up (and the issue of which filters to or not to prefill) came to front of the discussion, he said that it's fine to prefill the filters if you prefer to do so. Although he did say to prefill via the outer holes, so that the fuel that you are prefilling with is getting filtered
