I have a 2008 IC CE 300 School bus with the DT 466, EPA 04
I have a 2008 IC CE 300 School bus with the DT 466, EPA 04 blue engine. Somehow air is getting into the fuel system. The Bus will run fine, I'll shut it down and several house later i will come out, start it and it will run for approx 10 min, then runs rough and then quits. I then bleed the fuel system by pushing the shrader on the side of the engine just below the valve cover on the driver's side and pump the primer until the fuel runs without air. the bus will start and run fine. This problem is intermittent and does not do this every time. Sor far i have changed the fuel line and fittings from the tank to the filter head. Any suggestions? Thank you, Jared … read more
