n. a stoppage in a pipeline caused by gas bubbles (especially a stoppage that develops in hot weather in an internal-combustion engine when fuel in the gas line boils and forms bubbles that block the flow of gasoline to the carburetor) [syn: vapour lock]
Wikipedia
Vapor lock is a problem that mostly affects gasoline-fueled internal combustion engines.
It occurs when the liquid fuel changes state from liquid to gas while still in the fuel delivery system. This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling. Restarting the engine from this state may be difficult.
The fuel can vaporize due to being heated by the engine, by the local climate or due to a lower boiling point at high altitude. In 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.
Usage examples of "vapor lock".
If the needle goes a little too far, penetrates the lung, and if an air bubble then happens to be forced into a blood vessel and manages to travel all the way back to the heart without being absorbed, it is possible though extremely unlikely to get a sort of vapor lock in the valves of your heart-air embolism, the doctors call it.

Once I had a glass works going, I could make a vapor lock easily enough.
They're designed with a vapor lock, no oxygen can get down there, so no fire.
