True vapor lock is about as common as finding a chicken with lips, the Easter Bunny, or an honest politician. It's caused by the liquid gasoline upstream of the carburetor boiling and turning into a gas that can't be pumped. Unless you've got a metal fuel line lying on the exhaust pipe or something similar, try to find the real cause of the problem.
