I am in the middle of restoring a 65 GTO. The car came without an engine or transmission. All the power train is now in this frame off restoration. Putting in a 73 455. Where does the vent line go for the fuel pump. The mechanical fuel pump (73 455) has a vent line on the pump. Should I just use a Holley pump without a vent line. Not legal in Calif. This is a Calif. car. Getting confused with 65 versus 73 issues. Do I need a 65 vented fuel tank?
