I just thought I would show the masses what a 1971 fuel vent system is composed of. Apparently it is a one year only design? I can see why. The pictures show the vent lines that come out of the inner compartment inside the main tank and then run over to the vent tube that runs up inside the trunk area. There are four rubber lines coming from the tank to the vent tube and one steel line from the tube to the engine compartment where the canister would have been. You can see the plug on top of the tank for draining the inner compartment. I will show the workings of the tube if I remove it.
