Design Engineering Inc. - Undertank Insulation

Hot fuel reduces engine performance, stresses the fuel pump and can lead to vapor lock but DEI has come up with an effective kit to help combat this problem. Simply line the underside of your fuel tank with the self-adhesive Reflect-A-Cool material and trim to shape.


  • The DEI Reflect-A-Cool material is made up of an aluminized reflective foil backed with a base layer of glass fiber
  • Rated to withstand continuous temperatures up to 400 degrees and can reduce fuel temps by up to 30%
  • Installation is easy, the material can be cut with scissors and lays down well to cover irregular shapes.
  • Can be used with all tanks including metal, plastic and fiberglass
