Vapor Block™ solves the problem of fuel and other fluids boiling from extreme heat and causing a vapor lock situation.

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.
