    I have a 07 Columbia with a C15 Accert and it seems like every day I have to prime it up to get it started once it gets going good it runs all day sometimes if i idle for a few minutes it will lose its prime and shut off and I also noticed in my fuel water separator that is has bubbles in it, I’ve changed my check valve on the fuel filter house but cat told me my engine has 2 check valves in the fuel filter housing


    Please help !!!!

    When did it start? I would say your sucking air somewhere, check the fuel filters and make sure they are sealed up correctly.

    I am not too familiar with a c15, maybe someone else can help with the most common places
