Vapor Block by Design Engineering is specifically engineered to prevent vapor lock caused by extreme heat in fuel and fluid lines, a common issue that leads to rough idling and difficult engine starting.
By significantly reducing heat transfer to the fuel line, Vapor Block keeps fuel cooler and below its boiling point, ensuring consistent engine performance.
This sleeve features a convenient split design with an adhesive flap, allowing for quick, tool-free installation without the need to disconnect or remove the fuel line.
Simply wrap Vapor Block around the fuel line, peel off the adhesive liner, and press the flap securely in place.
Constructed from durable glass fiber and polyester, laminated with a reflective aluminum outer layer, Vapor Block provides excellent, long-lasting thermal protection.
It effectively shields fuel lines from radiant heat, helping to avoid costly repairs or modifications due to vapor lock.
This lightweight, reusable sleeve is ideal for automotive, marine, and industrial applications where managing heat is critical to reliable engine operation.
