What causes vapor lock in an engine?
What causes vapor lock in an engine?
Vapor lock happens when your fuel boils in your carburetor or your fuel line. Vaporized fuel creates back pressure in your fuel system and prevents gas from getting to your engine. It commonly occurs when a car has been idling or has been turned off and then back on.
What causes a vapor lock in an engine?
Vapor lock generally occurs when the fuel (usually gasoline) within the fuel delivery system overheats and vaporizes too rapidly. The resulting excess gas bubbles accumulate to the point of actually blocking normal fuel delivery.
What happens if you have a vapor lock in your fuel pump?
Result: Excess vaporization of fuel in the carburetor and/or actual vapor lock in the fuel line or fuel pump. Wrap the fuel lines on both sides of the pump with aluminum foil. Note: This is a precaution if your car is prone to vapor lock. It won’t help much once the problem has already occurred.
What to do when your car has vapor lock?
After your warmed engine stalls, pull to the side of the road. Open the hood. Place a bag of ice on the fuel line between the fuel pump and carburetor and the one that connects to the fuel pump to bring down the fuel line’s temperature and allow vapor fuel to condense. After a few minutes, try starting the engine.
How to prevent fuel vapor lock on a marine engine?
Add water or coolant if the radiator is low. The thermostat and cooling fan must be in proper working order — an engine that runs hot will vapor lock more readily. On marine engines, clean all obstructions from the engine cowl vents with a stiff brush.

How can I get rid of vapor lock on my fuel pump?
Pouring cold water on the fuel pump will cool down the system in no time. Make sure the ignition is OFF while you do the process. The cold water will liquefy the vapors quickly. It removes the blockage of vapors present inside the fuel pump and lines.
