It runs to the left side of truck through a hole in frame forward of the gusset that goes from the body side to the frame, then through a hole in that gusset and the up into the top of the box that encloses the gas filler hose. It has a metal return bend at he end of the hose (works fine without it unless you are fording some very deep water). Welcome I have a 63 econoline pickup. If you are having any trouble with the gas gauge make sure you run a ground wire from the gas tank to the frame.
