Description

The Design Engineering 10671 is a Vapor Block fuel line sleeve designed to prevent vapor lock by reducing heat in the fuel line. It is made from glass fiber and polyester laminated to an aluminum outer layer for thermal protection. This sleeve has a 3/8 inch inner diameter and is 3 feet long.

Installation is straightforward with a split design and adhesive flap, allowing for application without disconnecting the fuel line. The product offers long-lasting thermal protection. It is advised not to apply the sleeve directly to exhaust components.
