Post subject:  gas cap- vented, or non vented

ok guys, what years had vented gas caps?? was it all non emision era cars?? i currently have a non-vented on my 61(a no-no, i think). i may keep it and just disconnect the vent tube by the tank(under car). this would also stop the annoying spillage by the cap, right :? ??..............steve

All the caps were unvented until '70 (California) '71 (Federal/Canada), when a valve-regulated vented cap, called a "Pressure-Vacuum" cap, was introduced.
