Fuel gauge is a wire to the sender in the tank. Evap is a single line that runs up the drivers side. I think by 72 they had moved onto the cannister up front and not the odd setup behind the rear seat. But i'm not sure of that.

The fuel feed line runs up the pass side. There is a rubber hose at the back of the subframe to allow for body mount movement. Some cars had a second smaller line that ran parallel to the fuel feed line. It as actually a return line. Both ran to the fuel pump. I think either all AC cars or all HD cooling cars got the return line. My Z, an AC car, has a return line.
