fuel transfer

  1. fuel tank issues on 2011 cab and chassis

    Duramax Diesel
    2011 Duramax cab and chassis has fuel transfer problems. back tank seems to have some suction on it any time that you open the fuel cap. Truck runs out of fuel with 1/2 tank showing on the gage and front tank actually has quite a bit of fuel in it. Wondering where to start with troubleshooting...
