  • 02 GMC C3500HD with dual gas tanks, having problems with gas gauge and only using one tank. HELP!?

    We have an 02 GMC C3500HD with dual fuel tanks. We've been having a problem for the last few weeks with the gas gauge not reading correctly. Now it seems like the gauge only using the rear tank. We've replaced the fuel level sensor and the fuel pump balance control module. I want to bring it back in to the mechanic that we use, but I want to know what else should they be checking for. Please help!
