My 71 has a eec tank and has a vent hose from the filler tube to the top of the tank the rubber hose is about 4 inch long I do not see that on your first pic. Also the eec tank has a vent tube that goes up the passanger door pillar and comes back down and goes through the floor next to the line off the sending unit that runs up to the canister i did not see that in your last pic. that is not a eec tank
