Learn how to install 10AN reflective heat sleeving to protect fuel lines from radiant heat, plus key benefits and common mistakes to avoid.
Quick answer
Install 10AN reflective heat sleeving to shield fuel lines from radiant heat and ensure reliable fuel delivery in high-temperature areas. Follow the step-by-step process below to do it correctly.
Why reflective sleeving matters
Radiant heat from exhaust manifolds, turbochargers, and other hot components can raise fuel temperatures, leading to vapor lock and inconsistent fuel pressure. Reflective heat sleeving adds a protective layer that helps keep fuel lines cooler, supporting stable engine performance.
The DeatschWerks 20 ft. Reflective Heat Protection Sleeving is designed for -10 AN hose, giving you enough material to cover multiple sections or a long run. Its reflective surface bounces heat away, while the sleeving itself acts as a barrier.
Trade-offs and considerations
While reflective sleeving is effective against radiant heat, it does not provide significant insulation against conducted heat. If your fuel line touches a hot surface directly, you still need a physical heat shield or additional insulation.
The sleeving adds bulk and stiffness to the hose, which can make routing more challenging in tight spaces. Plan your routing before cutting to length, and use proper fasteners to keep the sleeving in place.
Installation steps
- Measure and cut: Measure the length of fuel line you need to protect, adding a few extra inches for overlap and securing. Cut the sleeving with sharp scissors or a knife. Checkpoint: Ensure the cut is clean and straight to prevent fraying.
- Slide over the hose: Slide the sleeving over the -10 AN hose before connecting the fittings. If the hose is already installed, you can use a lubricant or a wire pull to work the sleeving into place. Checkpoint: Avoid stretching the sleeving too much, as it may reduce its protective thickness.
- Position and secure: Position the sleeving to cover the areas most exposed to radiant heat. Use zip ties or heat-resistant clamps to secure both ends and any midpoints. Checkpoint: Make sure the sleeving does not slide or bunch up, which could leave gaps in protection.
- Route and verify clearance: Route the fuel line with the sleeving, keeping at least a small air gap from hot surfaces when possible. Verify that the sleeving does not rub against moving parts or sharp edges. Checkpoint: Re-check all fasteners after a short test drive to ensure nothing has shifted.
