I have an 871, so I have glossed over this fuel pump issue instead of paying detailed attention.
I've got a buddy that just recently bought a used truck with a 2250 with about 200k miles, do all 2250's have the three cylinder pump with ceramic plungers?
How would we determine if he has the ceramic plungers?
If not, how do I help him identify a three vs a two?

We are going to put a bypass filter on when we finish this current run.
We are also planning to do an EGR tune-up as well. He is not currently in a position to assume the financial risk of "doing the greatest longevity thing."
What else do I need to help or tell him to watch for?

THIS IS WHAT THE NEW 2 CYLINDER LOOKS LIKE
