Continuing the Fuel Sending Unit discussion

most of the time on a mopar, the ground strap from the fueltank sending unit to the fuel line isnt working, or is missing. tray a jumperwire from a CLEAN BARE METAL spot on the frame to a clean bare spot on the fuel line at the tank. the gage should work. if not, unhook the sending unit wire at the tank and ground that. the gage should go to full quickly.
