DEI Introduces Vapor Block™ Fuel Line Sleeve

A New Peel and Stick Low Profile Damping Material to Reduce Road and Engine Noise


DEI now offers an innovative fuel line solution for a problem common with carbureted early model vehicles – vapor lock. DEI’s new Vapor Block™ Fuel Line Sleeve provides an easy, sensible and low cost solution to prevent rough idling and difficult starting caused by vapor lock. Designed to greatly reduce heat in the line to keep the fuel cooler and below boiling, the DEI Vapor Block line sleeve 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 line, remove the adhesive release liner and press adhesive back flap into place.

Made of glass fiber and polyester laminated to an aluminum outer layer, it offers excellent long lasting thermal protection without the expense of paying for expensive repairs or modifications. Currently available in a 5/8” size with a 16mm inside diameter, it can be purchased online or wherever DEI line and hose protection products are sold.
