I replaced my gas tank with one from I think 74. My rig is a 69 so I don't have any place for the extra gas tank vents to go to. I've got three of them that need to be plugged. Well, after parking up on a snowbank during lunch, and having a lot of gas leak out of one of those vents while eating lunch, I'd really like to get them plugged! Anyone have any idea what to use to plug those? I heard brass pipe fittings would work. Any thoughts anyone?
