EVIL ENERGY AN8 PTFE Fuel Line Kit 16ft (0.394" ID) — Nylon-Braided, E85-Compatible, High-Temp

EVIL ENERGY 8AN PTFE Fuel Line Kit is a 16-foot, AN8 (0.394" ID) PTFE inner tube with a nylon braided outer jacket engineered for high-temperature, high-pressure automotive fuel systems including E85.

This PTFE fuel hose combines a smooth, chemically resistant inner Teflon-like liner with a durable nylon braid for abrasion resistance and routing stability. The hose is sized as -8 AN (13/32" / 0.394" inner diameter), has an overall outside diameter near 0.55", and ships in a 16-foot length for long runs or multiple shorter runs. It is rated to operate across extreme temperatures and pressures, compatible with gasoline, E85 blends, lubricants, and many coolants; however, the construction is relatively stiff and benefits from professional routing and installation.

What measurements and performance ratings should I verify before ordering?

Confirm the inner diameter, overall diameter, and required run length to ensure fittings and clamps will fit and that the hose will route without excessive bending. Check the pressure and temperature ratings against your system’s peak conditions to avoid over-stressing the line.

• Inner diameter: 13/32" (0.394 inch) — AN8 specification
• Outer diameter: ~0.55 inch
• Length: 16 feet (single continuous hose)
• Working temperature: -76°F to 446°F (-60°C to 230°C)
• Working pressure: up to 1,500 PSI; burst ≈ 4,500 PSI

How does this hose handle E85 and other aggressive fuels?

The PTFE inner liner provides excellent chemical resistance, making it suitable for ethanol-rich fuels like E85 as well as conventional gasoline, diesel, and many lubricants. The smooth bore also reduces deposit buildup and flow restriction compared with some rubber hoses.

• Compatible with E85, gasoline, diesel, lubricants, and many coolants
• PTFE liner resists swelling, corrosion, and chemical attack
• Nylon braid gives abrasion protection and improved abrasion resistance

Is installation straightforward, and what should I watch for?

The hose is stiffer than standard rubber lines, so it resists tight bending and should not be folded in half. For clean, leak-free connections, use AN8-compatible fittings and follow torque recommendations; professional installation is recommended for coil routing, flareless fittings, or when compression sleeves are required.

• Do not fold or sharply kink the hose — maintain recommended bend radius
• Use AN8 fittings or compatible adapters and correct sealing methods
• Inspect clamps and routing points to prevent chafing against sharp edges

Where is this hose best applied within a vehicle or system?

Because of its temperature and pressure ratings, this PTFE/nylon hose performs well in fuel delivery lines, return systems, and feed lines for upgraded fuel pumps or forced-induction setups. It also suits many high-temperature or chemically aggressive auxiliary systems where a robust, long-life fuel line is needed.

• Fuel feed and return lines on performance vehicles
• High-temperature engine bay routing and turbocharged applications
• Custom plumbing where chemical resistance is required

Who is this for: Mechanics, tuners, and DIY enthusiasts fitting high-flow or ethanol-capable fuel systems who need a long, chemically resistant AN8 line with strong temperature and pressure capability. If you require a flexible, easily bent hose for tight bends, consider alternatives; if you need durable, E85-safe plumbing and a continuous 16-foot run, the EVIL ENERGY 8AN PTFE fuel line kit is a practical choice.
