EVIL ENERGY AN6 PTFE Fuel Line Kit 10ft Black — E85-Compatible, High-Temp/High-Pressure

EVIL ENERGY's AN6 PTFE fuel line kit is a 10-foot, AN6 (5/16" ID) black PTFE hose assembly designed for high-temperature, high-pressure automotive fuel systems that accept E85 and other fuels.

This durable PTFE-lined, nylon-braided fuel hose delivers a chemical-resistant, temperature-tolerant solution for performance and race applications. Built to withstand a wide operating range and high pressures, the hose is intended for installations that require resistance to ethanol blends, gasoline, diesel, lubricants, and many coolants. The kit comes as shown in the product images and is sized to AN6 specification (5/16" inner diameter, 0.43" outer diameter) in a 10-foot length — please confirm measurements before installing.

How does this AN6 PTFE hose stand up to E85 and aggressive fuels?

The PTFE inner liner offers excellent chemical resistance against ethanol blends such as E85 and common automotive fuels, minimizing swelling and degradation over time. The nylon braid provides physical protection and added abrasion resistance under demanding conditions. While the material resists most petroleum-based and alcohol fuels, correct fittings and professional installation help maintain leak-free service.

• Compatible with E85, gasoline, diesel, lubricants, and many coolants
• PTFE liner prevents chemical reaction and fluid contamination
• Nylon braid improves abrasion and wear resistance
• Recommended to use correct-sized AN6 fittings and clamps for secure connections

What temperature and pressure limits can I expect from this hose?

This PTFE fuel hose operates across a wide temperature span from -76°F to 446°F (-60°C to 230°C), making it suitable for both cold starts and high-heat engine compartments. Its rated maximum working pressure is 1,500 PSI with a bursting pressure around 4,500 PSI, giving a strong safety margin for many high-performance fuel delivery setups. Always adhere to manufacturer pressure ratings and inspect the hose and fittings regularly for wear.

• Working temperature: -76°F to 446°F (-60°C to 230°C)
• Maximum working pressure: 1,500 PSI
• Bursting pressure: approximately 4,500 PSI
• Routine inspection recommended under high-stress conditions

How should I fit and install the EVIL ENERGY AN6 PTFE hose?

PTFE-lined hoses are relatively rigid compared with rubber hoses and should not be sharply bent or folded. For reliable results, plan routing with gentle curves, secure with proper clamps or mounting brackets, and use compatible AN6 fittings. If you lack installation experience, have a qualified technician complete the job to ensure safety and leak-free connections.

• Inner diameter: 5/16" (0.31") — AN6 sizing
• Outer diameter: 0.43" — check clearance in routing paths
• Length: 10 feet — cut to fit and terminate with AN6 fittings
• Do not fold or sharply bend the hose; professional installation recommended

What practical benefits does this kit provide for performance vehicles?

The PTFE construction resists chemical attack and helps maintain consistent fuel delivery characteristics in systems running ethanol blends or high-performance fuels. The braided exterior offers mechanical durability in engine bays and race environments, while the compact AN6 diameter fits many aftermarket setups. Combined, these features support safer, longer-lasting fuel plumbing for modified or high-output engines.

• Improved chemical resistance for ethanol and specialty fuels
• Durable braided jacket for abrasion protection
• Compact AN6 profile for tight engine compartments
• High temperature and pressure ratings for performance use

Who is this for: The EVIL ENERGY 6AN PTFE Fuel Line Kit is aimed at enthusiasts, fabricators, and professional shops that need an E85-compatible, high-temperature, and high-pressure rated AN6 fuel hose. It's ideal for performance cars, track vehicles, or any project requiring a chemically resistant PTFE liner and robust braided protection. Confirm AN6 sizing and routing needs before purchase, and consider professional fitting and installation for best results.
