The 68-74 has the fuel lines there. It looks like the 76 does too. The return line is 1/4” diameter. The supply line is 3/8. I know on the 68, the lines are located on top of the rail, not to the side. Thanks for the thorough videos.
That left side hardline is for the tank vent, going to the coal canister in the engine compartment. Why not terminating the chassis ground directly to the rear frame..?
@StingrayBob Mainly because I wanted the grounds centrally located. The black wire is now terminated at the battery. The brown wire is now terminated on the rear passenger head along with the 2 harness grounds.
