I've got a 71 Duster that I bought with the tank and filler tube out of the car because the trunk center was rotted out. Now that I've fixed the necessary, I ordered a new tank matching the one that came with the car - a single vent model. I went to install the tank and noticed there is nothing to connect the vent tube to. I looked in the parts book, and there is no vent tube for the car, just a single fuel line running front to back.

Can someone recommend the right way to vent this thing? I don't have the part in the trunk to use the 4-vent tank, and am not interested in correctness at all. I just need to be able to fill the tank and drive the car without an explosion hazard from venting fumes in the wrong way.

Thanks for any help with this.
