EVIL ENERGY 6AN PTFE Fuel Line Kit — 20ft Nylon-Braided Hose (AN6, E85 Compatible, 1500 PSI)

EVIL ENERGY 6AN PTFE Fuel Line Kit is a 20-foot, AN6 (5/16" ID) PTFE hose with nylon braid and AN fittings designed for high-temperature, high-pressure fuel delivery in E85, petrol, diesel and EFI applications.

This fuel line kit combines chemically inert PTFE tubing with a protective nylon braid and AN6 compatibility for fuel-injected engines, LS swaps and any installation that needs a flexible yet pressure-rated hose. The kit is engineered to withstand extreme temperatures and aggressive fuels, and it comes in a continuous 20-foot length so you can route, cut and assemble fittings to suit custom engine bays or replacement runs.

What are the technical limits and material benefits of this PTFE hose?

This line uses polytetrafluoroethylene (PTFE) as the inner tube for excellent chemical resistance, wrapped in a nylon braid for abrasion protection and routing control. It’s rated for continuous use from -76°F to 446°F (-60°C to 230°C) with a working pressure up to 1,500 PSI and a burst pressure around 4,500 PSI.

• Inner diameter: 5/16" (0.31 in), outer diameter: 0.45 in.
• Length: 20 ft (6 m) continuous run for custom routing.
• Temperature range: -76°F to 446°F (-60°C to 230°C).
• Pressure: 1,500 PSI working, ~4,500 PSI burst.

Can this hose handle E85, ethanol blends, and other aggressive fuels?

Yes — PTFE is highly resistant to chemical attack and compatible with ethanol, gasoline, diesel, lubricants and many coolants. The material resists swelling and degradation common to some rubber hoses when exposed to alcohol-based fuels.

• Suitable for E85 and high-ethanol-content fuels.
• Safe for common engine lubricants and coolants.
• Reduced fuel permeation compared with many rubber hoses.
• Recommended for fuel-injection systems subject to varied fuel chemistry.

How easy is installation and what should I watch for during fitting?

The kit’s 20-foot length gives flexibility for routing and trimming, but PTFE is stiffer than rubber hose and cannot be sharply folded. For reliable leak-free connections, use proper AN6 fittings and have a knowledgeable installer handle tight bends and termination points.

• Measure available routing path before cutting — hose is not foldable.
• Use AN6-compatible fittings and correct assembly technique.
• Avoid tight radius bends to prevent kinking or stress.
• Professional installation is recommended for engine swaps and high-pressure systems.

Is this the right choice for high-temperature engine bays and performance builds?

Absolutely — the PTFE core tolerates elevated under-hood temperatures and the nylon braid helps protect against abrasion and hot surfaces. With a high working pressure rating and compatibility with performance fuels, it’s well-suited to EFI conversions and LS-swap installations where durability and chemical resistance matter.

• High temperature tolerance up to 446°F (230°C).
• Pressure-rated for performance fuel systems.
• Nylon braid for mechanical protection in tight engine bays.
• Long 20 ft length for full vehicle runs or custom routing.

Who is this for: The EVIL ENERGY 6AN PTFE Fuel Line Kit is aimed at mechanics, custom fabricators and car enthusiasts performing LS swaps, EFI upgrades, or high-performance fuel system builds. Choose this hose if you need chemical resistance, high-temperature performance, and a pressure-rated AN6 solution; if you require flexible, foldable routing or DIY-only installation, consider consulting a professional first.
