EVIL ENERGY PTFE Fuel Hose 8AN (3/8" ID) 5ft Nylon-Braided for E85, High-Pressure 1500 PSI

EVIL ENERGY 8AN PTFE fuel hose is a 5-foot, 3/8" ID nylon-braided line engineered for E85 and high-performance fuel systems with wide temperature and pressure capability.

This braided PTFE fuel line combines a smooth, chemically resistant inner PTFE tube with a durable nylon outer braid to deliver reliable fuel transfer for performance engines, swaps and aftermarket plumbing. The hose measures 0.39 inch inner diameter and 0.55 inch outer diameter, comes in a 5-foot length and is built to resist a broad range of fuels and fluids including E85, methanol and common automotive oils. Installation instructions are included; measure your routing and bends before trimming to ensure proper fit and performance.

How tough is this hose under heat and pressure?

The EVIL ENERGY 8AN PTFE hose is rated for extreme operating ranges and high pressures typical of fuel-injection systems. It tolerates cold starts through hot operating conditions while maintaining structural integrity under high psi loads.

• Working temperature range: -76°F to 446°F (-60°C to 230°C).
• Maximum working pressure: 1500 psi; bursting pressure: 4500 psi.
• Minimum bend radius: 101.6 mm (4 inches) — avoid tighter bends to prevent kinking.

Which fuels and fluids can I run through this line?

This PTFE-lined hose resists chemical attack from a wide variety of automotive fluids, making it suitable for many fuel system and fluid-transfer applications. It's compatible with modern ethanol blends and several other liquids used in performance and everyday vehicles.

• Compatible with E85 gasoline, methanol, diesel and biodiesel blends.
• Suitable for transmission fluid, engine oil and other common automotive fluids.
• Appropriate for fuel supply, return, vapor or vacuum routing in engine bays.

Can I bend or route this hose through tight engine compartments?

The nylon braid adds strength but also increases stiffness compared with rubber hoses; the line resists kinking but requires mindful routing. Follow the minimum bend radius and consider using proper fittings to maintain sealing and flow.

• Minimum bend radius of 4 inches; do not fold or crease the hose.
• Professional installation recommended for tight or complex runs.
• For best results, pair with PTFE-compatible AN fittings such as EVIL ENERGY’s own fittings.

What sizes and installation guidance should I know before buying?

The 8AN sizing corresponds to a 3/8" inner diameter (0.39 inch) and a 0.55 inch outer diameter. Measure your existing lines and planned routing to confirm compatibility and allow room for fittings and clamps.

• Hose size: 8AN (3/8" ID / 0.55" OD), length: 5 feet.
• Installation instructions included; verify measurements before cutting.
• Because the braided PTFE hose is stiffer than rubber, plan connectors and mounting points accordingly.

This hose is designed for mechanics, tuners and DIY enthusiasts who need a chemically resistant, high-pressure fuel line for performance or replacement use. It is well suited to fuel injection plumbing, carburetor feed lines, LS engine swaps, boost and vacuum lines, and return or vapor routing. If you require flexible, low-bend routing in very tight spaces, or prefer softer rubber lines, consider routing or support brackets to avoid excessive stress. For the cleanest, most reliable installation pair this PTFE hose with compatible AN fittings and follow recommended bend radii and installation best practices.
