There is no vent line on a 69', the gas cap is vented.
Sounds like you have a sending unit for a 350 SS or a big block motor which had a 1/4" fuel return line. Look along your frame (passenger side) and see if the car has two steel fuel lines. If you don't have a return fuel line simply drop the gas tank and plug the 1/4" line coming out of the sending unit.
