EVIL ENERGY AN10 PTFE Fuel Line Kit — 10 ft Black (1/2" ID) E85‑Ready, High‑Temp 1,250 PSI

EVIL ENERGY's AN10 PTFE Fuel Line Kit is a 10-foot, AN10 (1/2" ID) black PTFE fuel hose built for E85 and high-temperature, high-pressure fuel systems.

This AN10 PTFE fuel hose from EVIL ENERGY combines a chemically resistant PTFE core with a nylon braided outer layer to deliver durability for ethanol blends, racing fuels, and demanding engine bays. With a 1/2" inner diameter, 10-foot length, and a working temperature range from -76°F to 446°F (-60°C to 230°C), it’s engineered for installations that require high pressure tolerance and minimal fuel permeation. Note that PTFE braided hoses are stiffer than rubber lines and require careful routing and professional fitting for best results.

How does this fuel line handle E85 and aggressive fuels?

The PTFE inner liner is inherently resistant to ethanol, methanol, and most aggressive fuel additives, reducing swelling and degradation compared with many rubber hoses. Its nylon braid adds abrasion resistance and helps the line keep shape under pressure.

• PTFE core resists chemical attack from E85 and high-ethanol blends.
• Nylon braid improves abrasion resistance and routing stability.
• Low fuel permeation helps maintain fuel integrity over time.

What are the pressure, temperature, and size specifications I need to know?

The hose measures 0.52" ID (1/2" nominal) and 0.69" OD with a total length of 10 feet, making it suitable for many AN10 applications. It has a working pressure of 1,250 PSI and a burst pressure rated at 3,750 PSI, and performs across a wide temperature span from -76°F to 446°F (-60°C to 230°C).

• Inner diameter: 0.52" (1/2").
• Outer diameter: 0.69"; total length: 10 ft.
• Working pressure: 1,250 PSI; burst: 3,750 PSI.
• Temperature range: -76°F to 446°F (-60°C to 230°C).

Can I bend, fold, or DIY-install this PTFE fuel hose?

Because of the PTFE core and nylon braid, this hose is relatively stiff and must not be folded in half; tight bends can cause kinking or stress at fittings. Professional installation is recommended to ensure correct routing, proper AN-style fittings, and leak-free connections.

• Do not double-fold or sharply crease the hose.
• Use appropriate AN10 fittings and adapters for secure seals.
• Plan routing to avoid excessive bends, heat sources, and sharp edges.

What accessories or preparations should I plan for before installation?

Measure the run precisely and include slack for vibration and thermal expansion; this kit includes the hose only, so you may need AN10 ends or hose end fittings. Use proper cutting tools and flaring or crimp fittings designed for PTFE-lined braided hoses to ensure a safe, reliable system.

• Check fitment and length against your vehicle’s routing before cutting.
• Purchase compatible AN10 hose ends, clamps, or adapters if not included.
• Use a certified installer or follow manufacturer fitting instructions.

Who is this for? This EVIL ENERGY AN10 PTFE fuel line kit suits performance builders, race teams, and enthusiasts upgrading fuel systems for E85 or other aggressive fuels who need a durable, high-pressure hose. If you want a chemically resistant line for turbo, EFI, or carbureted setups and are prepared to use proper AN10 fittings and professional installation, this 10-foot PTFE hose is engineered to meet those demands. If you need a more flexible rubber hose or pre-assembled ends, consider alternate products.
