DEI Vapor Block Sleeve - 3/8in x 36in

DEI Vapor Block is a fuel-line sleeve that prevents vapor lock by keeping fuel below its boiling point, eliminating the rough idle and hard starts caused by heat soak. Made from glass fiber and polyester laminated to an aluminum outer layer, it installs without disconnecting the line - just wrap it around, peel the adhesive liner, and press the flap closed. Easy to cut to size. Do not apply directly to exhaust components.
