Just a little update...Dually hasn't moved since it's maiden voyage, had to remove the instrument panel and related components and start ringing wires and chasing "repairs" done over the years, managed to loose install everything last night and looks like everything is working but the gas gauge...it goes to full peg on both tanks soon as the key turns on...looks like it's back under the truck I go....
