Your carb should have a provision for a large vacuum hose. In the front or the rear of the carb. Remove one of the breathers in the valve cover and put the pcv there. I suggest the rear one so you can put oil in the engine easier. The grommets are not the same for pcv and breather , so you will need a new grommet. Most auto parts store will have them. You will need one for aftermarket valve covers. They usually come in pairs. Use vacuum hose instead of fuel line. It will last longer. If your provision from the carb is already being used, you can put a "Tee" in it.
