EVIL ENERGY AN6 PTFE Fuel Line Kit 16ft (5/16" ID) — Stainless Nylon-Braided, E85-Compatible

EVIL ENERGY's AN6 PTFE fuel line kit is a 16-foot, 5/16" ID stainless-steel braided hose engineered for high-temperature, high-pressure automotive fuel systems compatible with E85 and most automotive fluids.

Built for performance engines and professional installs, this AN6 PTFE (Teflon) line combines a smooth PTFE inner core with a protective nylon/stainless braid to resist chemical attack, heat, and abrasion. The 16-foot length and -6 AN sizing (5/16" ID) suit custom routing and retrofit work on racecars, hot rods, or upgraded street vehicles. Before ordering, confirm diameter and routing needs because PTFE lines are stiffer than rubber hoses and require careful handling and proper fittings.

How does this PTFE AN6 line handle high temperatures and pressures?

The EVIL ENERGY PTFE hose is rated for a wide operating range and strong pressure tolerance. Its PTFE inner liner resists softening at high temperatures while the braided jacket maintains structural integrity under pressure.

• Working temperature: -76°F to 446°F (-60°C to 230°C)
• Maximum working pressure: 1,500 PSI
• Bursting pressure: 4,500 PSI
• PTFE core resists thermal degradation and most fuels

Is this hose compatible with E85 and other automotive fluids?

Yes—PTFE is chemically inert to a wide range of fuels and fluids, making this AN6 line suitable for ethanol blends such as E85 as well as gasoline, diesel, lubricants, and many coolants. Confirm fittings and clamps are also compatible to ensure a leak-free system.

• Compatible media: E85, gasoline, diesel, lubricants, coolants
• PTFE inner liner resists ethanol-induced swelling or breakdown
• Use approved AN fittings and proper sealing techniques

What should I know about installation and handling?

This stainless-steel/nylon braided PTFE hose is considerably stiffer than rubber fuel hose and cannot be folded sharply. For safe, long-lasting installations, plan routing, avoid sharp bends, and have fittings professionally assembled if you lack experience.

• Inner diameter: 5/16" (0.31 in); outer diameter: 0.45 in
• Length: 16 ft — cut to fit; measure before purchase
• Do not fold or sharply kink; use proper bend radius and supports
• Professional installation recommended for AN fittings and crimps

Which vehicles and projects commonly use this AN6 PTFE line?

This hose suits performance upgrades, engine swaps, and custom fuel system builds where higher pressure tolerance and chemical resistance are needed. It’s commonly chosen for race cars, modified street cars, and any build using ethanol blends or requiring durable, long-lasting fuel lines.

• Performance and race vehicle fuel systems
• Turbo or high-pressure EFI applications
• Custom engine swap plumbing or long routing runs
• Vehicles using E85 or mixed-fuel setups

Who is this for: EVIL ENERGY’s 6AN PTFE fuel line kit is designed for mechanics, fabricators, and enthusiasts who need a robust, chemically resistant hose for high-pressure fuel systems. If you’re planning a professional-grade installation, using ethanol fuels, or upgrading to an AN6 plumbing standard, this braided PTFE line delivers the heat, pressure, and chemical resistance expected in motorsport and custom automotive applications. If you prefer flexible, easy-to-bend hose for simple OEM replacements, consider a different, softer fuel hose instead.
