EVIL ENERGY 8AN PTFE Fuel Hose 3/8" ID 5ft — E85-compatible, Nylon Braided, 1500 psi

EVIL ENERGY 8AN PTFE Fuel Hose is a 3/8" ID, nylon-braided, E85-compatible 5-foot line engineered for high-temperature, high-pressure fuel and fluid routing.

This 8AN PTFE hose combines a smooth PTFE inner tube with a rugged nylon braided outer jacket to deliver resistance to aggressive fuels like E85 and methanol, plus a wide operational temperature range. Designed for automotive and motorsport use, it supports fuel injection, return lines, vacuum, boost, and other fluid-transfer roles where durability and chemical compatibility matter. The line ships in a 5-foot length and includes installation guidance; precise measurement and professional installation are recommended because the hose has limited flex compared with softer rubber lines.

What operating temperatures and pressures can this hose handle?

The EVIL ENERGY 8AN PTFE hose is built for demanding conditions, with a working temperature range from -76°F to 446°F (-60°C to 230°C). It’s rated to 1500 psi working pressure and has a bursting pressure around 4500 psi, providing a wide safety margin for most automotive and industrial fluid applications.

• Working temperature: -76°F to 446°F (-60°C to 230°C)
• Working pressure: up to 1500 psi
• Burst pressure: approximately 4500 psi
• Minimum bend radius: 4 inches (101.6 mm)

Which fluids and systems are compatible with this PTFE line?

The PTFE inner core is chemically inert to a broad range of fluids, making this hose suitable for E85 gasoline, diesel blends, biodiesel, engine oil, transmission fluid, methanol, and water. Its compatibility makes it useful for fuel injection systems, return lines, vapor or vacuum lines, and many engine-swap plumbing tasks where standard rubber hoses may degrade.

• Safe with E85, methanol, diesel, and biodiesel
• Compatible with engine oil and transmission fluids
• Suitable for fuel supply, return, vacuum, and boost lines
• Not recommended to fold sharply—retain smooth bends above minimum radius

How does the hose install and what should I know before fitting it?

The hose comes in a 5-foot length and includes installation instructions; however, because the braided PTFE assembly is relatively stiff, professional installation is advised for best results. Measure your routing path before cutting or fitting; ensure bends stay larger than the 4-inch minimum radius and use compatible 8AN PTFE fittings for leak-free connections.

• Included length: 5 feet (cut to fit as needed)
• Inner diameter: 0.39 inch (3/8" ID); outer diameter: 0.55 inch
• Minimum bend radius: 4 inches—avoid tight folds or kinks
• Recommended: use EVIL ENERGY PTFE fittings for optimal sealing

Will this hose work for performance or swap projects?

Yes—built to withstand high pressures and aggressive fuels, this 8AN PTFE line suits performance engines, LS swaps, and turbo setups that need reliable fuel delivery or return plumbing. It provides chemical resistance where standard rubber hoses might soften or fail, though its stiffness requires planning for secure clamps and routing supports.

• Ideal for fuel injection and return lines in performance builds
• Good choice for vapor, vacuum, and boost plumbing
• Stiffer than rubber hoses—plan mounting points and supports
• Length and size fit common 8AN applications in automotive projects

Who is this for: The EVIL ENERGY 8AN PTFE Fuel Hose is aimed at mechanics, performance vehicle builders, and anyone doing engine swaps or custom fuel-system work who needs a chemical-resistant, high-pressure 3/8" ID line. If you require E85 or methanol compatibility and a hose that tolerates extreme temperatures and pressure, this nylon-braided PTFE assembly is a strong option—just measure carefully and consider professional installation to ensure correct routing and leak-free fittings.
