EVIL ENERGY AN-6 PTFE Fuel Hose Kit 25FT — 6AN (3/8") E85-Compatible Nylon-Braided, High-Temp

This kit supplies 25 feet of 6AN (3/8") inner-diameter PTFE hose with a durable nylon braid, plus the fittings needed for EFI LS engine conversions, turbo feed lines, fuel returns, and other high-pressure automotive uses. Designed to tolerate aggressive fuels and wide temperature swings, the hose offers a safer, longer-lasting alternative to rubber lines in performance and retrofit projects.

What components come in the kit and what size is the hose?

The kit includes 25 feet of AN-6 (internal diameter 5/16" / 0.31", outside diameter 0.45") PTFE hose with a nylon braid and the matching AN-6 fittings shown in product images. Measure your existing lines and fittings before installing to ensure compatibility.

• Hose ID: 5/16" (0.31") — chosen for AN-6 applications
• Hose OD: 0.45" — confirm clearance routing
• Includes anodized AN-6 fittings and end hardware as pictured
• 25 feet length — enough for most LS swaps and conversions

How durable is the hose under heat, pressure, and E85 fuel?

This PTFE core with nylon outer braid is engineered for wide temperature ranges and high pressure. It resists degradation from ethanol-blended fuels (including E85) and holds strength at elevated temperatures common near engines and turbos.

• Temperature range: -76°F to 446°F (-60°C to 230°C)
• Working pressure: up to 1,500 PSI; bursting pressure: approximately 4,500 PSI
• Compatible with gasoline, ethanol blends, lubricants, and many coolants

Can I bend and route this hose like flexible rubber lines?

The PTFE core and braid make the hose more rigid than soft rubber lines; sharp bends or folding can damage the interior and reduce flow. Plan routing with smooth curves, use proper clamps, and avoid tight pinch points or kinks.

• Avoid folding the hose in half — permanent damage may occur
• Use gentle radii and secure mounting points to prevent vibration wear
• Professional installation is recommended for EFI and turbo systems

Where is this hose best used in a vehicle?

It’s intended for fuel injection systems, LS engine swaps, turbo oil/fuel feed lines, return lines, transmission cooler lines, and similar high-temperature or high-pressure pathways. The chemical compatibility and pressure ratings make it suitable for many automotive fluid duties.

• EFI fuel lines and LS swap fuel supply/return
• Turbocharger fuel or oil feed and return lines
• Transmission oil cooler lines and vacuum or vapor return lines

Who is this for: This EVIL ENERGY AN-6 PTFE fuel hose kit is aimed at mechanics, performance enthusiasts, and professional shops performing EFI conversions, LS engine swaps, turbo installations, or any application requiring an E85-compatible, high-pressure hose. If you need a robust, chemically resistant line with AN-6 fittings and a substantial length for routing, this kit provides the hardware and hose to complete most installs; however, because of the hose stiffness, skilled installation and correct routing are recommended to get reliable, long-lasting results.
