So would that be the canister that mounted on the frame behind the the L/Frt wheel. It had a 1/4" metal fuel line that ran from the Tank(s) to the canister. Then it had a 3/4" flexy tube that ran up to the back of the air cleaner. The canister had a mushroom shaped vent in the center of it.

Or the 76-77 had the rectangular canister mounted to the firewall on the passenger side of the engine compartment. With similar hookups for vapor return depending on CA or Federal emissions

That's what I remember. (77 pictured below)

Condensation/expansion tank behind the driver seat. Four lines go to it. One vent (vapor) line from main tank. One vent (vapor) line from aux tank. One return (liguid) line to main tank. Last line (vapor) goes to charcoal canister.
