EVIL ENERGY 6AN PTFE Fuel Line Kit 20ft Black — Nylon-Braided, E85-Compatible, 1500 PSI

EVIL ENERGY 6AN PTFE Fuel Line Kit is a 20-foot, AN6 (6AN) PTFE inner hose with a nylon braid exterior designed for high-temperature, high-pressure automotive fuel systems including E85-compatible applications. This kit supplies a continuous 20 ft (6 m) length of PTFE-lined fuel hose with AN6 dimensions suitable for many performance and replacement plumbing jobs. The hose combines a chemically resistant PTFE inner core with a durable nylon braided jacket to resist abrasion and keep fuel flows stable under challenging conditions. It’s engineered for automotive fuels, lubricants and coolants and rated for a broad temperature range, making it a versatile option for engine bays, racecars and custom fuel routing.

What size and pressure ratings does this 6AN PTFE hose have?

The hose has an internal diameter (ID) of 5/16" (0.31 in) and an outer diameter (OD) of 0.45". It is specified for typical AN6 fittings and measured to provide reliable flow for common 6AN fuel fittings. Pressure and temperature specs help you match the line to your system.

• ID: 5/16" (0.31 in), OD: 0.45 in — fits standard AN6 hardware
• Working temperature: -76°F to 446°F (-60°C to 230°C)
• Maximum working pressure: 1,500 PSI; bursting pressure: 4,500 PSI

Is this PTFE hose safe to use with E85 and other fuels?

The PTFE inner liner offers strong chemical resistance, making it compatible with ethanol blends such as E85 as well as gasoline, diesel, and many lubricants. The external nylon braid protects the core from scuffs and mechanical wear common in engine bay installations. Always inspect fittings and clamps for compatibility with ethanol fuels because some materials can degrade over time.

• PTFE core resists ethanol, gasoline, diesel and most lubricants
• Nylon braid reduces abrasion and helps maintain routing integrity
• Recommended for fuel system, return lines, and high-temp applications

How should I install and handle the PTFE nylon braided hose?

The hose is relatively stiff compared with rubber lines and is not intended to be sharply folded. For safe, long-lasting installation, plan smooth routing paths and avoid tight bends; use proper AN6 fittings and clamps. Installation by an experienced technician is recommended to ensure leak-free connections and correct heat shielding where needed.

• Do not fold or sharply bend; maintain gradual curves
• Use proper AN6 fittings and torque specifications for fittings
• Consider heat shielding or routing away from extreme heat sources

What practical uses and environments suit this fuel line kit?

This PTFE nylon braided hose is built for demanding automotive environments where temperature, pressure and chemical exposure are concerns. It is well suited to performance vehicles, race teams, and anyone upgrading stock fuel lines for improved durability or E85 conversion. The continuous 20-foot length allows cutting to size for multiple connections or custom runs.

• Performance fuel delivery, return lines, and tank-to-engine plumbing
• High-temperature or high-pressure applications in engine bays
• Custom installations where E85 compatibility is required

Who is this for? This EVIL ENERGY 6AN PTFE Fuel Line Kit is for mechanically minded vehicle owners, fabricators, tuners and race teams who need a chemically resistant, high-temperature hose in a standard AN6 size. Choose this kit when you require a long, continuous length to cut to size, when routing through tight engine compartments with abrasion risk, or when converting to ethanol fuels. If you’re unsure about bending or fitting technique, professional installation will ensure safe, leak-free operation and longer service life.

FAQ

Q: Can this hose be used with E85 fuel?

A: Yes. The PTFE inner liner is compatible with ethanol blends like E85, gasoline and many lubricants.

Q: Can I bend the hose sharply to fit tight spaces?

A: No. The PTFE nylon braided hose is relatively stiff—avoid sharp bends and use gradual curves or fittings.
