EVIL ENERGY AN10 PTFE Fuel Hose 20ft Black — Nylon-Braided, E85-Compatible High-Pressure Line

EVIL ENERGY AN10 PTFE fuel hose is a 20-foot, AN10 (0.52" ID) PTFE-lined, nylon-braided fuel line engineered for high-temperature, high-pressure automotive fuel systems including E85 and methanol blends.

This heavy-duty fuel hose combines a smooth PTFE inner lining with a tough nylon braid to resist chemical attack, reduce permeability, and stand up to demanding engine bay environments. With a wide operating temperature range and a high working pressure, it is built for performance applications such as fuel injection, return lines, vacuum or boost plumbing, and LS engine swaps. The kit ships as a 20-foot length with installation guidance — measure carefully before cutting.

How does this hose handle modern fuel blends like E85?

The PTFE inner liner is chemically inert, making it resistant to ethanol, methanol, and many aggressive fuels that can degrade rubber hoses. The nylon braid adds abrasion resistance and structural support so the hose keeps shape and function under pressure.

• Compatible with E85, methanol, biodiesel, gasoline, diesel, and engine oil
• PTFE liner reduces swelling and fuel permeability
• Nylon braid protects against chafing and heat exposure

What temperature and pressure limits should I expect?

This AN10 fuel line works across a very broad thermal window and is rated for high-pressure systems common in performance engines. It’s suitable for both cold starts and sustained high-temperature operation when properly installed.

• Operating temperature: -76°F to 446°F (-60°C to 230°C)
• Maximum working pressure: 1250 psi; burst pressure: 3750 psi
• Minimum bend radius: 114.3 mm (4.5 inches); avoid sharp folds

Can I use this hose for fuel injection, return lines, or vacuum plumbing?

Yes — its internal PTFE surface and robust outer braid make it suitable for fuel injection feed lines, return lines, vapor or vacuum lines, and many other under-hood applications. It performs best when routed with proper fittings and supported to prevent excessive bending.

• Common uses: fuel injection hose, boost line, carb fuel line, LS swap fuel line
• Also compatible with transmission fluid and engine oil where AN10 size fits
• Professional installation recommended for tight bends or complex routing

What should I know before cutting and fitting this hose?

The 10AN PTFE hose is comparatively stiff and should not be sharply folded or creased. Use the correct AN10 PTFE fittings for a secure seal, and follow the included installation instructions to avoid leaks or reduced life.

• Inner diameter: 0.52 inch; outer diameter: 0.69 inch; length: 20 feet
• Avoid folding the hose in half or forcing tight radii; follow the 4.5" minimum bend radius
• Evil Energy recommends using matching PTFE AN fittings for best results

Who this is for: Drivers and fabricators building or upgrading fuel systems who need a chemically resistant, high-pressure AN10 line that tolerates ethanol blends and high under-hood temperatures. Ideal for performance builds, LS swaps, custom fuel rails, and any application where a durable PTFE-lined hose is preferred. If you need flexible routing with extremely tight bends, consider alternate hose options or professional routing to preserve hose life.
