Old school looks with modern Heatshield technology! HP Heat Shield Kits feature a heat protective thermal sleeving capable of withstanding 1200-degrees Fahrenheit continuously. This nonflammable fuel line heat shield has a special weave that allows it to expand and contract over fittings, terminals, and more. These sleeves can protect fuel lines, preventing vapor lock. They can also be used to protect wires from heat damage and allow you to hide your wiring. The ½-inch id sleeve is ideal for shielding most Harley and motorcycle fuel lines, helping to stop vapor lock and improve performance. The smaller 5/16 inch sleeve is great for small wire looms and brake lines. The 5/8 inch inside diameter sleeves are ideal for protecting your oil lines from heat damage caused by being too close to the motor or exhaust. Try the 1-1/4 inch inside diameters sleeves for your sport and moto bike radiator lines. So add some heat protection and make your ride a cooler one with this fuel line heat shield!

HP Builder's Kit Installation Tips

  • To expand ID of sleeve, bunch or shrink the overall length of sleeve
  • To decrease ID stretch overall length
  • Secure ends of sleeve with Thermal-Tie, clamp, wire, or high temp electrical tape

PRO TIP - As provided by Bryan Fuller of Fuller Hot Rods, use some heat shrink tubing on the ends to give it an OEM look.

The following conversion is a guide for AN hoses only. The conversion reflects the most common conversions for AN hose sizes, however there may be some variances with different manufacturer's. Always double check by measuring the OD of your hose. Always verify the OD of your hose, you may use a caliper or sliding an open end wrench over the hose. If you are still unsure verify with the manufacturer of the hose as to their specific OD. By using this calculator you acknowledge this is a guide only and it is ultimately your responsibility to verify the correct OD of your AN line.








Q. Will my Builder Kit Burn?

A. No, HP Builder’s Kit is made from a noncombustible fiberglass, even if surrounding fluids combust, the sleeve will not burn, and whatever is inside it will not burn.

Q. How do I get the sleeve to expand over fittings and terminals?

A. Compress or “bunch” the sleeve length wise, and stretch the opening of the sleeve then slide over. It may also help to coat fitting or terminal with silicone or dry graphite spray before sliding over.
