The Thermaflect Sleeve Quick Test: How Our Fuel Line Protective Sleeve Stops Vapor Lock

The summer’s been hotter than a sauna in the seventh level of hell. For anyone with a carbureted engine, that means the risk of vapor lock increased dramatically.

If you’re a racer, it can put the car on the trailer well before you’re ready to leave the track. But proper use of thermal barriers can prevent vapor lock, no matter how hot the day gets.

Vapor lock happens when the temperature of the fuel heats up enough to transform it from liquid to vapor. And since fuel pumps are designed to pump liquid, not air, vapor lock effectively starves the engine of fuel. Without the proper volume or pressure of fuel, the car will run rough or completely stall.
