Magwakeenercew2jh, the fuel pump I have has one inlet and two outlets. One for the carb,which is a threaded flare fitting. And a smaller barb type, which is a vapor return line, that runs back to the fuel tank. My guess is that its part of the emissions control system. Also maybe to help reduce vapor lock?
