BRIFITOR AN6 25ft PTFE Fuel Line Kit — AN6 3/8" Stainless-Nylon Braided, E85-Compatible with 26 Fittings

BRIFITOR's AN6 25ft PTFE fuel line kit is a complete, E85-compatible braided hose system including 26 aluminum AN fittings and tools for professional-grade fuel, oil, or coolant plumbing.

If you need a flexible, chemical-resistant fuel line package for EFI swaps, LS conversions, or general fuel-system plumbing, this kit supplies 25 feet of PTFE core hose wrapped with stainless nylon braid plus a wide assortment of AN6 fittings. The kit is built for high temperatures and pressures, designed to accept gasoline, diesel, alcohol blends (including E85), and many hydraulic fluids. It includes assembly tools so you can crimp and assemble fittings cleanly and repeatably.

How durable is this PTFE fuel hose under heat and pressure?

The hose uses a PTFE inner liner with a nylon/stainless steel braid to resist abrasion, chemicals, and temperature extremes. Rated performance covers a broad operating range and high burst strength for demanding engine bay conditions.

• Inner diameter: 0.31" (8 mm); outer diameter: 0.44" (11.3 mm)
• Operating temperature: -76°F to 446°F (-60°C to 230°C)
• Working pressure: up to 3000 PSI; burst pressure: up to 10000 PSI
• PTFE core resists fuels, oils, alcohol blends including E85

Which fittings and tools come with the kit and what do they do?

The kit bundles 14 aluminum AN6 PTFE hose fittings, socket nuts, hose separator clamps, and sealing plugs for flexible routing and leak-free connections. It also provides a dedicated AN wrench and a hose assembly tool to simplify cutting, inserting, and tightening the PTFE fittings.

• 14x AN6 6061-T6 aluminum PTFE hose fittings with anodized finish
• 8x socket nuts and 2x separator clamps for neat routing
• 2x male flare plugs with hex head for sealing unused ports
• 1x adjustable AN fittings wrench and 1x PTFE hose assembly tool included

Can I use this hose kit for EFI LS swaps and ethanol fuels like E85?

Yes — the PTFE inner liner is chemically inert and compatible with gasoline, diesel, and ethanol blends, making it suitable for EFI conversions and modern high-alcohol fuels. The stainless/nylon braid provides additional abrasion resistance for installation in tight engine compartments.

• Engine swaps: EFI LS systems and aftermarket fuel rails
• Fuel types supported: petrol, diesel, pump gas, oil, E85, alcohol
• Also suitable for: transmission lines, coolers, and some hydraulic applications
• Recommended: professional installation or use of included assembly tools

What should I know about installation and safety?

Professional installation is recommended to ensure leak-free connections and correct routing away from heat sources and moving parts. Use the included AN wrench and assembly tool for precise tightening and avoid over-bending the hose near fittings.

• Trim hose squarely and insert PTFE liner fully before tightening
• Do not reuse damaged fittings or hose sections; replace if cut or nicked
• Check all connections for leaks at initial startup and after heat cycles
• Use clamp hardware supplied for secure mounting and separation

Who is this for: The BRIFITOR AN6 25ft PTFE fuel line kit suits professional mechanics, tuners, and experienced DIYers performing EFI conversions, LS swaps, or upgrading fuel and cooler plumbing. It's ideal when you need a long run of E85-compatible, high-temperature fuel hose with all the core fittings and specialty tools included to assemble a reliable system.
