Or should I just keep aware and keep my eye open for it? I have a ISX CM2350 in a 17 KW T680. Maybe it’s not even an issue anymore either like it was before I don’t know.

The general consensus is to replace the guts (tappets, plungers, rollers etc.) of the fuel pump every 400k miles (or equivalent hours or so) as a preventative measure if you own a common rail ISX engine (CM2250/CM2350). This re regardless of what type of plungers etc. you have in it.

Here is a typical scenario ...

Thank you, I will plan on it. Mine is a 17 truck with a CM 2350 2013 engine. 239k Miles. I’ll plan on this maintenance in the next year
