Vapor Block Fuel Line Sleeve; 0.375-Inch x 36-Inch (Universal; Some Adaptation May Be Required)

Fuel Line Heat Protection. The Vapor Block Fuel Line Sleeve, measuring 0.375-inch inside diameter by 36 inches in length, is engineered to prevent vapor lock by significantly reducing heat transfer to fuel lines. It helps maintain fuel temperature below boiling point, preventing rough idling and difficult engine starts. This sleeve can be wrapped around existing fuel lines without disconnecting them, providing an effective thermal barrier for enhanced vehicle performance.

Construction and Appearance. Vapor Block is made from multiple layers, including fiberglass and polyester laminated with an aluminum outer surface, offering exceptional thermal insulation. Its split design allows the sleeve to be wrapped around lines and sealed securely with an adhesive flap. The durable silver metallic finish resists harsh automotive conditions.

Installation. Installation is straightforward and requires no special tools or fuel line disconnection. Simply wrap the sleeve around the line, peel off the adhesive backing, and press the flap to secure it firmly in place, making this an accessible upgrade for most users.

Application. Suitable for universal applications; some adaptation may be required. Not intended for direct contact with exhaust components.
