What Is Vapor Lock, And Why Does It Happen?
WebOct 22, 2024 · Vapor lock is what happens when enough bubbles of gasoline vapor collect in a particular location to prevent a pump that is designed to pump liquid fuel, not vapor, from delivering fuel to an engine. The problem is exacerbated by suction pumps, which reduce the absolute pressure of the fuel.

Such pumps were typically located higher than the fuel tank, were directly heated by the engine and fed fuel directly to the float bowl inside the carburetor. Fuel was drawn under negative pressure (gauge pressure) from the feed line, increasing the risk of a vapor lock devel… hazbin hotel rating age
