I just finished re-plumbing an old Stovebolt that had plasic tubing-like you use on your swamp-cooler-for fuel line from the rear tank to the valve by the left rocker panel. It went through holes in the frame,over the frame,across the driveline,around the frame rail,through a hole in the crossmember,made a big loop ahainst the floorboards,and went across the driveline again,over the frame rail into the change over valve.(about 15 feet of tubing) Runs a TON better now.
