EVIL ENERGY 6AN PTFE Fuel Line Kit 26ft — E85-Capable EFI Hose with Nylon Braid, High Temp/1500 PSI

EVIL ENERGY's 6AN PTFE Fuel Line Kit is a 26-foot, E85-capable, high-temperature and high-pressure fuel hose assembly designed for LS swaps and EFI applications.

Built for performance engines and modern fuel systems, this kit combines a PTFE core with a nylon braided jacket to deliver chemical resistance, wide temperature tolerance, and the pressure capacity needed for EFI and alternative fuels like E85. The hose features a 6AN (5/16" ID) sizing, a durable outer braid, and comes with fittings as pictured — ideal when replacing stock lines or building custom hardline runs where corrosion resistance and fuel compatibility matter.

Will this hose work with my LS swap and E85 fuel setup?

Yes—this kit is formulated to handle common gasoline blends including E85 and is sized for many LS swap fuel system needs. Check inlet/outlet fitting sizes and available routing space before ordering to ensure compatibility.

• Inner diameter: 5/16" (0.31 in) — matches 6AN sizing
• Length: 26 ft (7.9 m) — allows long runs or multiple lines
• Fuel compatibility: gasoline, E85, lubricants, and many coolants
• Includes fittings as shown in product images for direct installation

How does this PTFE hose handle heat and pressure in EFI systems?

The PTFE core provides excellent chemical stability while the nylon braid adds mechanical strength, enabling safe operation across a broad temperature range and under high system pressures. This makes the line suitable for engine bays with high underhood temperatures and modern fuel pump output.

• Operating temperature: -76°F to 446°F (-60°C to 230°C)
• Maximum working pressure: 1,500 PSI
• Bursting pressure: 4,500 PSI for added safety margin
• Robust braid resists abrasion and external wear

How do I install and route this PTFE fuel hose in my vehicle?

The hose has a relatively stiff construction due to the PTFE core and braid, so it should be routed with care and avoided tight bends. Professional installation is recommended to ensure correct bend radii, leak-free fittings, and proper support along the run.

• Do not fold or sharply bend the hose; maintain smooth curves
• Use proper clamps and supports to prevent chafing and vibration
• Verify fitting torque and sealing before pressurizing the system
• Measure available length and clearances prior to trimming

What fittings, sizes, and accessories come with the kit?

The package includes the 26-foot PTFE hose and the fittings shown in the product photos to help you build or repair a fuel line. Confirm the included fittings match your components and plan for any adapters you may need.

• Standard 6AN-compatible fittings included (see images for specifics)
• Cut to length for custom assemblies or multiple line runs
• Adapters may be required for non-AN connections or factory ports
• Professional crimping or clamp-style connections recommended

Who is this for? This EVIL ENERGY 6AN PTFE Fuel Line Kit suits tuners, engine builders, and DIY mechanics installing LS swap or EFI systems who need a long, durable, and E85-compatible fuel hose. It's most appropriate for users comfortable measuring and routing a stiffer PTFE hose or who plan to have the kit fitted by a professional. If you require flexible rubber lines for tight bends or quick DIY swaps, consider alternative hose types; for high-temp, high-pressure, and chemical-resistant runs, this kit is a solid choice.
