Hey folks,
Just finished the first fuel filter service on the truck (2025 Cummins 3500) with 10,420 miles on it. First off, kind of a pain to do. Was able to open the drain valve on the front filter but not the rear. Eventually tried to use a Phillips screwdriver in the head of the plastic drain cap on the rear filter and it immediately rounded out, so be careful if you attempt the same. Eventually I just decided not to drain the rear and it went a lot more smoothly from that point. A flexible head ratchet is definitely required for the job.
Anyhow, truck seems to be running well now in the 8 miles or so I put on it after the job, but as I was driving I noticed that I now have a check engine light illuminated. I’ve read a couple other posts saying it may take a day or two to remove trapped air and that should reset the light. Anyone else experience this? Unfortunately I don’t have a code reader. Thanks.
