Injection pump

Has anyone changed The pump due to ceramic plungers braking. I hear if they brake it goes through engine and destroys it. I think in the 600 hp Cummins. Mine is a 2012. Trucker forum says it’s not if they will brake but when. The do have a upgrade out changing them out to steel plungers.

    Had to have fuel injector pump on my ISC changed last year. New pump was $6000 plus labor. Don't know about the 600HP but Cummins seems to be very proud of their fuel pumps.

    Doubt you’ll put on enough miles for the ceramic plungers to start failing…300,000+.
