EVIL ENERGY 8AN PTFE Fuel Hose 20FT Black — AN8 Nylon-Braided, E85-Compatible, High-Temp/High-Pressure

EVIL ENERGY's 8AN PTFE fuel hose is a 20-foot, AN8-rated, nylon-braided PTFE line built for high-temperature, high-pressure fluid routing including E85-compatible fuel systems.

Engineered for performance builds and demanding automotive applications, this EVIL ENERGY AN8 fuel line combines a PTFE (Teflon) inner tube with a protective nylon braid to deliver chemical resistance, wide temperature tolerance, and reliable pressure handling. With a 0.39-inch inner diameter and 0.55-inch outer diameter, the hose is supplied in a 20-foot length and is intended for professional installation where bending limits and proper fittings are observed.

How does this hose perform under heat and pressure?

The EVIL ENERGY 8AN PTFE hose maintains integrity across an expansive temperature range and is rated for high working pressures, so it’s suitable for many performance fuel systems. It resists common fuels and fluids while preserving flow characteristics even in elevated temperatures.

• Working temperature: -76°F to 446°F (-60°C to 230°C)
• Maximum working pressure: 1500 psi; burst pressure: 4500 psi
• Minimum bend radius: 101.6 mm (4 inches) — avoid sharp folds

Is this line compatible with E85 and other fuels?

Yes — the PTFE inner tube resists aggressive fuels and many automotive fluids, making the hose compatible with E85, methanol, diesel blends, transmission fluid, and engine oil. That chemical resistance helps prevent swelling, degradation, and permeability common in some rubber hoses.

• Suitable for E85 gasoline and methanol
• Works with diesel, biodiesel, transmission fluid, and engine oil
• Also usable as vacuum, vapor return, or fuel return lines

What fittings and installation considerations should I know?

The hose is relatively stiff compared with soft rubber lines, so it requires appropriate AN8 PTFE-compatible fittings and careful routing to respect the minimum bend radius. EVIL ENERGY recommends professional installation for best results and compatibility with their PTFE fittings.

• ID 0.39 inch and OD 0.55 inch — verify AN8 sizing before ordering
• Includes installation instructions; measure before cutting
• Avoid folding; use proper clamps and EVIL ENERGY PTFE fittings when possible

Where does this hose work best in a vehicle?

This 8AN PTFE line is versatile for fuel delivery and related systems on performance engines, swaps, and retrofit projects. Use it where chemical resistance, temperature tolerance, and consistent inner surface are priorities for reliable flow.

• Fuel injection lines, fuel supply and return systems
• Boost control, vacuum lines, and vapor return plumbing
• LS swaps, carburetor feed lines, and engine bay fuel routing

Who this is for: Builders and mechanics working on high-performance or modified vehicles who need an E85-compatible, high-temperature, AN8-sized fuel hose. If you require a durable PTFE inner liner, high pressure capability, and compatibility with a broad set of fuels and fluids — and you can follow the recommended bending and fitting guidelines or have a pro install it — this EVIL ENERGY 8AN PTFE fuel hose is designed to meet those needs.
