EVIL ENERGY 6AN PTFE Fuel Line Hose 20ft (5/16 in ID) E85 Nylon-Braided, High-Temp 1,500 PSI

This fuel line kit combines a chemically inert PTFE inner liner with a durable nylon braided jacket to handle aggressive fuels and harsh engine bay conditions. The hose measures 5/16" inside diameter (approximately 0.31 inch), 0.45 inch outside diameter, and comes as a 20-foot (6 m) length so you can route fuel to and from tanks, filters, pumps, and engines without splices. Built for high-temperature and high-pressure environments, the kit is suited to performance vehicles, race cars, and engine swaps where E85 or exotic fuels are used.

What makes this PTFE hose suitable for E85 and performance fuels?

PTFE (polytetrafluoroethylene) resists chemical attack far better than common rubber hoses, so the inner liner withstands ethanol blends and other corrosive additives. The outer nylon braid adds abrasion resistance and helps prevent expansion under pressure, which preserves consistent fuel delivery.

• Chemically inert PTFE inner liner compatible with gasoline, E85, lubricants, and coolants.
• Nylon braid reduces cut and abrasion risk in tight engine bays.
• High maximum working pressure (1,500 PSI) keeps lines stable under pump surge.

How does the hose perform under heat and pressure?

This PTFE hose is built to operate across extreme temperatures, from deep cold to intense engine heat, while maintaining structural integrity. With a bursting pressure rated around 4,500 PSI, it provides a wide safety margin for most automotive fuel system demands.

• Operating temperature range: -76°F to 446°F (-60°C to 230°C).
• Maximum recommended working pressure: 1,500 PSI for typical fuel system use.
• Burst pressure approximately 4,500 PSI for robust overload protection.

How should I plan installation and routing for a 20 ft AN6 hose?

Because PTFE hose is comparatively stiff, avoid sharp bends and do not fold it in half. Pre-measure routing runs and allow gentle sweep radii; professional installation or proper AN fittings are recommended to ensure leak-free joints and long-term reliability.

• Measure before cutting — full 20 ft length needs planning for routing and fittings.
• Use AN6-compatible fittings for leak-proof connections and correct sealing.
• Maintain gradual bends; do not crease or sharply kink the PTFE liner.

Which vehicles and projects benefit most from this kit?

The EVIL ENERGY 6AN PTFE hose is ideal where fuel compatibility and pressure resilience matter: performance street cars, race vehicles, custom fuel system builds, and engine swaps using ethanol blends. Its construction helps ensure consistent flow and fuel integrity in demanding conditions.

• Performance and race cars running E85 or modified fueling systems.
• Custom or replacement fuel lines for swaps and aftermarket pumps.
• Applications needing high temperature and chemical resistance.

Who is this for: installers, tuners, and enthusiasts who need a durable, chemically resistant AN6 fuel line for E85 or similar fuels. If you require a flexible rubber hose for tight bends, consider alternative hoses; if you need chemical stability, high temperature tolerance, and strong pressure ratings for performance fueling, this EVIL ENERGY PTFE kit is a solid choice. Professional installation is advised to ensure proper fitting, routing, and safety compliance.
