Prevent rough idling and difficult starting caused by vapor lock with DEI Vapor Block™. Vapor Block™ fuel line sleeve was specifically developed to prevent vapor lock in fuel systems by greatly reducing heat in the line to keep fuel cooler and below boiling. Vapor Block™ installs easily with a split design and adhesive flap. There is no need to disconnect the fuel line to install. Simply wrap Vapor Block™ around the line, remove the adhesive liner and press the adhesive flap into place.
