EVIL ENERGY 6AN 90 Degree Swivel Hose End Fittings – 2PCS Aluminum AN6 CPE Fuel Hose Adapters

Designed for CPE Stainless Steel and Nylon Braided Fuel Hose

The EVIL ENERGY 6AN 90-degree hose ends are intended for compatible CPE-lined braided hose assemblies.

CPE, or chlorinated polyethylene, is commonly used as a synthetic rubber liner in performance automotive hoses.

When paired with correctly matched hose dimensions, reusable AN fittings allow enthusiasts to build custom-length fuel lines without relying on preassembled hose kits.

Compatible Hose Types

• Compatible stainless steel braided CPE fuel hose

• Compatible nylon braided CPE fuel hose

• Manufacturer-approved -6AN rubber-lined braided hose

Important: These fittings are not automatically compatible with PTFE-lined hose. PTFE fuel hose generally requires a dedicated PTFE hose end with a different internal retention design.

Always verify the hose liner material, inside diameter, outside diameter, and manufacturer-approved fitting compatibility before assembly.

360-Degree Swivel Design for Easier Fuel Line Installation

One of the biggest advantages of these EVIL ENERGY fittings is the integrated swivel feature.

The 360-degree swivel design allows the fitting to be oriented during assembly, helping reduce hose twisting and simplifying installation in confined engine compartments.

This is particularly useful when connecting braided fuel lines to aftermarket fuel rails, pressure regulators, fuel filters, and other components.

The swivel feature is intended for installation and positioning. It should not be treated as a continuously rotating fluid joint.

Precision 37-Degree AN Flare Sealing

These 6AN hose ends use a 37-degree AN flare connection designed to seal against a compatible male AN fitting.

The 9/16-18 UNF threads provide the mechanical clamping force needed to secure the flare surfaces.

Unlike tapered pipe threads, AN fittings seal at the flare rather than through the threads.

Installation tip: Do not apply PTFE tape or pipe-thread sealant to the AN flare connection. Inspect both sealing surfaces before assembly to help prevent leaks.

Ideal for Custom Fuel Systems and Engine Swaps

EVIL ENERGY 6AN 90-degree fittings are suitable for numerous custom fuel plumbing applications, including:

• Aftermarket fuel rail inlet and outlet connections

• Fuel pressure regulator installations

• Custom fuel supply and return lines

• LS engine swap fuel systems

• Turbocharged Honda and Acura builds

• Nissan SR20DET and KA24 fuel plumbing

• Toyota 2JZ performance fuel systems

• Compatible fuel filter and pump connections

Are CPE Fuel Hoses Compatible with E85?

CPE-lined hoses are commonly used in performance gasoline fuel systems, but their compatibility with ethanol blends depends on the specific hose formulation and manufacturer rating.

Not every CPE hose is approved for prolonged E85 exposure.

For dedicated E85 applications, PTFE-lined fuel hose is often preferred because of its chemical resistance and low fuel vapor permeability.

Important: These EVIL ENERGY CPE hose ends should not be installed on PTFE hose unless the manufacturer specifically approves the combination.

EVIL ENERGY 6AN 90 Degree Hose End Specifications

The maximum operating pressure and temperature of a completed hose assembly are limited by the lowest-rated component, including the hose, fitting, and seals.

What Vehicles Do These EVIL ENERGY 6AN Hose Ends Fit?

These fittings are universal aftermarket fuel plumbing components rather than direct-fit OEM replacement parts.

They can be used on a wide range of vehicles equipped with compatible custom -6AN fuel hose assemblies.

Fitment note: Vehicle compatibility depends on the installed hose construction, fuel system connections, and available mounting clearance. OEM quick-connect fittings and factory fuel lines may require additional adapters.

How to Install EVIL ENERGY 6AN 90 Degree Hose Ends

1. Relieve fuel system pressure and follow the vehicle manufacturer’s safety procedures.

2. Verify the fittings are compatible with the selected CPE-lined braided hose.

3. Measure the required hose length, accounting for fitting insertion depth and routing.

4. Cut the hose squarely using an appropriate hose-cutting tool.

5. Prepare the braided hose end according to the fitting manufacturer’s instructions.

6. Install the reusable hose end components, ensuring the hose is properly seated.

7. Tighten the fitting according to the manufacturer’s assembly specifications.

8. Connect the 37-degree female AN flare to a compatible male -6AN connection.

9. Position the 90-degree elbow to avoid sharp bends, abrasion, and hose twisting.

10. Pressure-test the completed fuel line and inspect all connections for leaks before operating the engine.

Avoid overtightening aluminum fittings, which can damage threads or sealing surfaces.

EVIL ENERGY 6AN 90 Degree vs. Straight Hose Ends
