Vapor lock can be caused by a kink in the gas line going to the engine. What happens is that the fuel is turned into a gas before actually reaching the engine, causing your car to stall (like it’s out of gas). If you have vapor lock, try popping the hood and following the gas line coming from the engine.
Vapor lock usually affects carbureted engines. it is the formation of an air bubble inside the carburetor or intake that prevents gas from going to the cylinders
Excessive heat near a fuel line prior to the fuel pump (diaphragm) can cause the fuel to vaporize, and most fuel pumps at that point won’t draw in and pump fuel at that point..
Vapor lock happens when fuel in the fuel line near the engine gets hot from the heat of the engine or the exhaust system and vaporizes into a bubble in the line. Fuel pumps are not designed to pump vapor, only liquid. So when that bubble of vapor hits the fuel pump, the pump stops moving fuel and your car acts like it’s out of fuel. After the engine cools down, the vapor returns to a liquid state, and the problem usually goes away. It only really happens on older carbureted vehicles with one fuel pump located on the engine. New cars have high pressure fuel pumps in the fuel tank, so if there was a bubble anywhere in the line, it would get pushed through rather than getting stuck at the fuel pump.
Liquid fuel changes state from liquid to vapor while still in the fuel delivery system. The fuel can vaporise due to being heated by the engine, by the local climate or due to a lower boiling point at high altitude. Regions where higher volatility fuels are used during the winter to improve the starting of the engine, the use of “winter” fuels during the summer can cause vapor lock to occur more readily.
Excessive heat caused by a variety of things causes the fuel in the lines to boil and that causes vapor lock.If you have a reoccurring problem with vapor lock you may have to reroute the fuel line away from sources or heat and in a real bad case you may have to insulate the fuel line.
