EVIL ENERGY PTFE Fuel Hose 10AN 1/2" ID 20ft Nylon-Braided E85-Compatible High-Temp

Built with a PTFE inner liner and a protective nylon braid, this 10AN fuel hose accepts E85, methanol, diesel blends and many automotive fluids while tolerating wide temperature swings. The 20-foot length and 0.52-inch internal diameter make it suitable for engine swaps, fuel return lines, vacuum and vapor lines, or custom fuel-routing jobs where durability and chemical compatibility matter. Installation instructions are included, and the hose performs best when paired with quality PTFE fittings.

How will this hose handle high temperatures and pressure?

The EVIL ENERGY 10AN PTFE hose is rated to work from -76°F to 446°F (-60°C to 230°C) and withstands a continuous working pressure up to 1250 psi, with a burst pressure listed at 3750 psi. Those ranges cover most automotive and racing environments where heat and pressure are factors, giving reliable flow under demanding conditions.

• 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)

What fluids and systems is this PTFE hose compatible with?

Designed with a chemically inert PTFE core, this hose resists degradation from gasoline blends (including E85), methanol, diesel and many lubricants. It’s suitable for fuel injection, fuel return, vapor or vacuum lines, and can also carry transmission fluid or engine oil in retrofit setups—making it a versatile option for performance builds.

• Compatible with E85, methanol, diesel, biodiesel and gasoline
• Accepts transmission fluid, engine oil and water in many applications
• Useful for fuel injection, carburetor and return lines
• Accepts vacuum and vapor routing where PTFE properties are required

How do size and installation affect performance?

The hose has an inner diameter of 0.52 inch and an outer diameter of 0.69 inch; choose fittings and clamps sized to match the 10AN specification. At 20 feet, the length allows flexible routing for swaps and custom plumbing, but note the construction is relatively stiff—sharp folding or kinking is not recommended. Professional installation or at least careful routing and proper PTFE fittings will ensure best results.

• Internal diameter: 0.52 inch (10AN)
• Outer diameter: 0.69 inch
• Total length: 20 feet; measure before purchase
• Stiff braid construction—avoid folding in half and respect bend radius

What should I know about fittings and long-term use?

For reliable sealing and longevity, use compatible PTFE-rated fittings—EVIL ENERGY recommends their own PTFE fittings for optimal interface performance. Regular inspections for abrasion where the braid contacts chassis components and ensuring clamps are sized correctly will prolong service life. Avoid extreme bending to prevent stress at the fittings and the PTFE liner.

• Recommended pairing: EVIL ENERGY PTFE fittings for best sealing
• Inspect for abrasion and routing wear periodically
• Maintain recommended bend radius to prevent stress and leakage
• Professional installation is advised for complex or high-pressure systems

Who is this for: The EVIL ENERGY 10AN PTFE fuel hose is aimed at performance enthusiasts, mechanics performing engine swaps, and fabricators who need a chemical-resistant, high-temperature fuel line for E85 or specialty fuels. Choose this hose when you need a durable, long-length PTFE solution for custom fuel routing, but plan fittings and routing carefully to match its stiffness and pressure capabilities.
