Description
Vapor lock can cost you a race or strand you on the road—fuel boils under extreme underhood temperatures, creating vapor bubbles that starve your engine of fuel pressure. The DEI Vapor Block Sleeve eliminates this risk with proven thermal protection, wrapping your fuel lines in a laminated glass-fiber and aluminum barrier that keeps fuel in liquid form where it belongs. Installation takes minutes with the split design and adhesive flap; no special tools or fabrication required.
