EVIL ENERGY 6AN PTFE Fuel Line Kit 20 ft — E85-Compatible, High-Temp 1500 PSI

EVIL ENERGY 6AN PTFE Fuel Line Kit is a 20-foot, E85-compatible 6AN (5/16" ID) braided PTFE fuel line system engineered for high-temperature, high-pressure EFI and LS swap applications. This kit delivers a corrosion-resistant PTFE core with a nylon braided outer jacket and 6AN fittings designed for modern fuel systems that run gasoline, ethanol blends (including E85), lubricants and coolants. With a working temperature range from -76°F to 446°F (-60°C to 230°C) and a rated working pressure up to 1,500 PSI (burst 4,500 PSI), it aims to provide durable routing for installations where fuel compatibility and heat resistance matter.

Will this hose work for my LS swap or EFI conversion?

Yes — the 6AN PTFE hose is commonly used in LS swaps and aftermarket EFI systems because of its chemical compatibility and pressure ratings. Its 5/16" (0.31") inner diameter matches typical 6AN plumbing, and the 20 ft length gives flexibility for routing in larger engine bays.

• Inner diameter: 5/16" (0.31 inch) suitable for 6AN fittings
• Outer diameter: 0.45 inch for standard AN clamp and fitting sizes
• Length: 20 ft (6 m) to cover long runs or multiple lines
• Compatible with E85 and most automotive fluids

How durable is the PTFE hose under heat and pressure?

The PTFE core and nylon braid resist heat and chemical attack far better than many rubber hoses. The hose is rated to operate from -76°F to 446°F (-60°C to 230°C), with a maximum working pressure of 1,500 PSI and a burst pressure around 4,500 PSI, making it suitable for high-demand fuel systems.

• Operating temperature window: -76°F to 446°F (-60°C to 230°C)
• Working pressure: up to 1,500 PSI for EFI applications
• Burst pressure: approximately 4,500 PSI for safety margin
• Nylon braid protects the PTFE from abrasion and kinking

Are there any installation considerations or limitations?

This PTFE hose is stiffer than conventional rubber lines and should not be folded or sharply bent; planning routing and using proper AN fittings and clamps is essential. Professional installation is recommended for complex builds to ensure leak-free connections and correct routing away from extreme heat or moving parts.

• Do not fold or crease the hose; avoid tight radius bends
• Measure and cut precisely; use compatible 6AN fittings
• Secure with clamps and route clear of exhaust and sharp edges
• Consider professional installation for EFI/LS swap complexity

What fluids can I run through this PTFE fuel line?

EVIL ENERGY PTFE fuel lines are formulated to be compatible with common automotive fuels, including gasoline and ethanol blends (E85), and can also carry many lubricants and coolants used in vehicle systems. Always verify compatibility if you plan to run specialty chemicals outside typical automotive applications.

• E85 and regular gasoline compatibility stated by manufacturer
• Suitable for many engine lubricants and coolant routing where specified
• Not intended for solvents or chemicals outside automotive use without verification
• Refer to your vehicle and fluid manufacturer recommendations

Who is this for? If you are swapping in an LS engine, installing an aftermarket EFI system, or upgrading old rubber lines for a fuel setup that demands higher temperature and pressure tolerance, this 20 ft EVIL ENERGY 6AN PTFE kit is tailored to those needs. It suits mechanics and experienced enthusiasts who need E85 compatibility and long hose runs; however, if you lack installation experience, plan to have a professional assemble and route the lines to ensure safe, leak-free operation.

FAQ

Q: Is this hose safe for E85 fuel?

A: Yes. The EVIL ENERGY PTFE line is rated for E85 and common automotive fuels, designed for chemical compatibility with ethanol blends.

Q: Can I bend the PTFE hose tightly around fittings?

A: No. The PTFE hose is relatively stiff and must not be folded; use proper routing and AN fittings with correct bend radii.
