How does DEI Vapor Block Sleeve prevent vapor lock?

Vapor lock occurs when fuel gets too hot and turns into vapor, hindering starting. This sleeve uses a special construction of glass fiber, polyester, and an aluminum outer layer to significantly reduce heat transfer to the fuel line, keeping the fuel cooler and liquid.

Is this sleeve difficult to install?

No, installation is straightforward. The sleeve has a split design and an adhesive flap, allowing you to simply wrap it around the fuel line and press the flap into place without needing to disconnect the line.

Can I use this sleeve on other parts besides fuel lines?

Yes, the Vapor Block sleeve is versatile and can be used on any cable, hose, or line that requires added heat protection. Just ensure you do not apply it directly to exhaust components.

Product Details

If you're dealing with a car that's hard to start, especially after it's been sitting in the heat, you might be experiencing vapor lock. This happens when fuel gets too hot in the line and turns into vapor, preventing the fuel pump from delivering liquid fuel to the engine. DEI's Vapor Block sleeve is designed to tackle this problem head-on by keeping your fuel lines cooler.

This sleeve is made from a combination of glass fiber and polyester, laminated to an aluminum outer layer. This construction is really effective at blocking heat from reaching your fuel line, which helps keep the fuel below its boiling point. It's a simple, wrap-around design with a built-in adhesive flap, meaning you don't even need to disconnect your fuel line to install it. Just wrap it around the line, peel off the backing, and press it shut. You can also easily cut it to the exact length you need for a custom fit on any hose or line where you need extra heat protection, just be sure not to apply it directly to exhaust components.
