EVIL ENERGY 6AN PTFE Fuel Hose 5/16" ID 10ft — Stainless Braided, E85 & High-Temp Rated

This 6AN PTFE hose combines a smooth chemical-resistant inner core with a stainless-steel braided cover to give you a durable, low-friction fuel line that tolerates a wide temperature range and aggressive fuels. Designed for installations from fuel injection and return lines to vacuum and boost plumbing, it arrives with installation instructions and is optimized for use with AN fittings to ensure secure, leak-resistant connections.

Will this hose handle E85 and other aggressive fuels?

Yes. The PTFE inner liner resists ethanol blends like E85, methanol, biodiesel and most common automotive fluids without degrading. The stainless braid protects the core and helps maintain shape and pressure integrity under load.

• Material: PTFE inner core resists chemical attack from ethanol and methanol.
• Outer: stainless-steel braided cover for abrasion and heat protection.
• Compatible fluids: E85, gasoline, diesel, engine oil, transmission fluid, methanol, water.

What temperature and pressure can this 6AN line withstand?

The hose is rated to operate across extreme temperatures and sustain significant pressure for demanding automotive applications. Always follow the minimum bend radius and installation guidance to avoid premature wear.

• Operating temperature: -76°F to 446°F (-60°C to 230°C).
• Maximum working pressure: 1500 psi; burst pressure: 4500 psi.
• Minimum bend radius: 3.5 inches (88.9 mm) — do not fold sharply.

How do I size and install this hose for my vehicle?

This product has a 5/16" internal diameter (0.31" ID) and a 0.43" outer diameter, supplied as a 10-foot length. Measure your runs and plan for bends that respect the minimum radius; professional installation is recommended for best sealing and routing.

• Dimensions: ID 0.31" (5/16"), OD 0.43", length 10 ft.
• Includes printed installation instructions and recommends matching AN fittings.
• Hose is relatively stiff; avoid tight folding and kinking during routing.

What applications is this 6AN PTFE hose suited for?

This hose works for a wide range of engine and chassis fluid paths — from fuel delivery to vacuum and return lines. Its PTFE core and braided jacket make it versatile for swaps, upgrades and custom plumbing where chemical resistance and pressure tolerance matter.

• Common uses: fuel injection supply, fuel return, carburetor lines, boost/vacuum plumbing, vapor return.
• Popular in LS swaps, custom fuel systems, turbo setups and race prep where E85 or methanol may be used.
• Works with transmission fluid and engine oil when routed and fitted properly.

Who is this for? If you’re a mechanic, fabricator, racer or enthusiast planning a custom fuel system or engine swap that requires reliable chemical resistance, high-temperature tolerance and pressure stability, this EVIL ENERGY 6AN PTFE stainless-braided hose is built for those demands. It’s ideal when using ethanol blends like E85, when long runs are necessary, or when you need a hose that resists abrasion and collapse under pressure. Note that due to its stiffness and required bend radius, this hose suits installations where proper fittings and careful routing are available; consider pairing it with EVIL ENERGY PTFE-compatible AN fittings for optimal performance.
