I'm considering installing a 2nd fuel tank(rt side). The rt side has been damaged where the angle mounts had been and am thinking about replacing rt bed side. If I do I'll get one with a fuel door. Here is the question. Does anyone know how to and what is needed to plumb the 2nd tank in? I have a 82 1/2 ton gas parts truck with duel tanks but don't think the installation is the same for gas and diesel. I also have a m1008 that I can rob it's tank. As always, thanks.
