2016/11/17Vapor lock happens when the temperature of fuel gets high enough to transform liquid into a vapor state. Fuel pumps are designed to pump liquid, not air, and the increased pressure inside the fuel lines keeps the fuel pump from being able to keep the fuel moving. The result is fuel starvation causing the engine to run rough or completely stall.
