EVIL ENERGY 6AN PTFE Fuel Line Kit 20FT – Black Nylon Braided E85 Fuel Hose
Upgrade your performance fuel system with the EVIL ENERGY 6AN PTFE Fuel Line Kit, featuring 20 feet of black nylon braided hose engineered for compatible E85, gasoline, and custom EFI fuel plumbing applications.
Built around a chemically resistant PTFE inner liner, this -6AN fuel hose is designed for demanding automotive environments where conventional rubber fuel lines may not provide the desired resistance to ethanol-rich fuels, elevated temperatures, or high operating pressures.
The hose features a 5/16-inch (0.31-inch) inside diameter, 0.45-inch outside diameter, and 20-foot length, making it a versatile option for custom fuel supply lines, return lines, LS engine swaps, turbocharged builds, and aftermarket fuel system installations.
EVIL ENERGY advertises a maximum working pressure of 1,500 PSI, a burst pressure of 4,500 PSI, and an operating temperature range of -76°F to 446°F.
With its black nylon braided exterior, the hose also provides a clean, understated appearance for performance engine bays.
Important: This is a universal custom fuel plumbing product. Use only hose ends specifically designed for the supplied PTFE hose. The exact fitting assortment must be confirmed from the product gallery before advertising the kit as complete.
Why Choose the EVIL ENERGY Black Nylon Braided PTFE Fuel Hose?
A performance fuel system must deliver sufficient fuel while maintaining chemical compatibility and reliable connections.
Fuel line construction becomes especially important when converting a vehicle to E85 or modifying an engine for increased fuel demand.
The EVIL ENERGY 6AN PTFE hose combines a chemically resistant inner liner with a black nylon braided exterior for custom automotive plumbing.

PTFE Inner Liner for E85 and Ethanol Fuel Compatibility
One of the main advantages of PTFE fuel hose is its resistance to a wide range of automotive fluids.
E85 contains a high percentage of ethanol, making fuel system material selection particularly important.
The PTFE liner is suitable for contact with ethanol-rich fuel blends, including E85, when the complete hose assembly uses compatible fittings and seals.
Why PTFE Fuel Hose Is Popular for E85 Conversions
PTFE is valued for its chemical stability and low permeability compared with many conventional hose materials.
These characteristics make it useful for custom fuel systems where ethanol compatibility is a priority.
However, converting a vehicle to E85 requires more than replacing the fuel hoses.
Fuel pumps, injectors, regulators, filters, seals, and engine calibration must also support the intended fuel.
For more information, read our technical guides:
How to Convert to E85 – Upgrading Fuel Lines
This article explains important considerations when upgrading fuel lines for an ethanol fuel conversion.
Our E85 conversion guide covers additional modifications involved in preparing a gasoline-powered vehicle for ethanol-rich fuel.
Black Nylon Braided Exterior
The EVIL ENERGY 6AN hose features a black nylon braided outer covering.
This exterior helps protect the hose from incidental abrasion while providing a discreet appearance for custom engine bay installations.
Black braided fuel hose is especially popular among builders who prefer an OEM-inspired or understated engine bay instead of brightly colored stainless braided lines.
Benefits of Black Nylon Braided Fuel Hose
-
Clean appearance for custom engine compartments.
-
Abrasion protection during normal service.
-
Suitable for routing through compatible engine bay locations.
-
Less visually prominent than bright stainless braided hose.
-
Complements black AN fittings and performance fuel system components.
The nylon exterior does not eliminate the need for proper routing, clamps, heat shielding, or abrasion protection where required.
1,500 PSI Working Pressure and High-Temperature Capability
EVIL ENERGY advertises the PTFE hose with a maximum working pressure of 1,500 PSI and a burst pressure of 4,500 PSI.
These values refer to the manufacturer’s stated hose specifications.
The completed hose assembly may have a lower allowable pressure depending on the hose ends, adapters, seals, and installation method.
Temperature Specifications
| Measurement | Rating |
|---|---|
| Minimum operating temperature | -76°F (-60°C) |
| Maximum operating temperature | 446°F (230°C) |
| Maximum working pressure | 1,500 PSI |
| Burst pressure | 4,500 PSI |
Safety note: These specifications do not automatically establish suitability for gasoline direct-injection high-pressure circuits or common-rail diesel injection systems. Those applications require components explicitly approved for the system.

Ideal for LS Swaps and Custom EFI Fuel Systems
The EVIL ENERGY 6AN PTFE fuel line can be incorporated into compatible custom EFI installations.
Common engine platforms include GM LS engines, modified Honda engines, turbocharged Nissan platforms, Toyota 2JZ engines, and other performance applications.
LS Engine Swap Applications
Potential applications include custom fuel supply or return plumbing for:
-
LS1 5.7L
-
LS2 6.0L
-
LS3 6.2L
-
LS6 5.7L
-
LQ4 and LQ9 6.0L
-
LM7 and other 5.3L LS-based engines
The correct fuel line size depends on the engine’s fuel consumption, operating pressure, line length, and acceptable pressure loss.
Is 6AN Fuel Hose Large Enough for E85?
A -6AN fuel hose may be appropriate for certain E85 systems, but suitability cannot be determined by AN size alone.
E85 generally requires greater fuel volume than gasoline for comparable engine operation.
Higher-output engines may require larger supply lines or different fuel system layouts.
