Complete 12-Piece Fitting and Clamp Package
The EVIL ENERGY 6AN fuel line kit includes a selection of reusable swivel hose ends designed to accommodate different installation angles.
| Included Component | Quantity |
|---|---|
| 6AN CPE nylon braided fuel hose | 20 feet |
| Straight swivel hose ends | 4 |
| 45-degree swivel hose ends | 2 |
| 90-degree swivel hose ends | 2 |
| 180-degree swivel hose ends | 2 |
| Hose separator clamps | 2 |
| Total fittings and clamps | 12 |
The package includes 10 hose end fittings and two separator clamps, not 12 fluid connection fittings.
Straight, 45°, 90°, and 180° Hose Ends
Different fitting angles make it easier to route fuel and fluid lines through crowded engine compartments.
Three-Layer CPE Fuel Hose Construction
The EVIL ENERGY 6AN hose uses a multilayer design intended to provide strength, flexibility, and protection in compatible automotive applications.
CPE Rubber Inner Liner
The inner layer is manufactured from chlorinated polyethylene (CPE) synthetic rubber.
This material is used in certain automotive hose applications involving gasoline, diesel, engine oil, and other compatible petroleum-based fluids.
304 Stainless Steel Reinforcement
The reinforcement layer uses 304 stainless steel wire to help resist internal pressure and support the hose structure.
This contributes to the manufacturer’s advertised working and burst pressure ratings.
Black Nylon Outer Braid
The external nylon braid provides additional abrasion protection and a clean appearance suitable for custom performance engine compartments.
Although the outer braid helps resist ordinary wear, the hose must still be routed away from sharp edges, moving components, and excessive exhaust heat.

Important: Not for E85, E10, or Methanol
Unlike some PTFE-lined fuel hoses, this EVIL ENERGY CPE hose is explicitly listed as incompatible with E85, E10, and methanol.
Do not use this hose for dedicated ethanol or methanol fuel systems.
Because standard retail gasoline can contain ethanol, confirm that your intended gasoline blend is approved by EVIL ENERGY before installation.
For additional information, read our How to Convert to E85 – Upgrading Fuel Lines technical guide.

Engine oil feed and return plumbing where specifications permit
Fitment note: This is a universal aftermarket kit. It does not directly replace factory fuel lines without suitable adapters and installation modifications.
6AN Fuel Hose vs. 8AN Fuel Hose
Choosing the appropriate fuel line size depends on fuel demand, pressure loss, hose length, and fuel system configuration.
| Feature | 6AN Fuel Hose | 8AN Fuel Hose |
|---|---|---|
| Nominal AN size | -6AN | -8AN |
| Packaging | More compact | Requires more space |
| Typical use | Custom fuel supply and return lines | Larger fuel delivery systems |
| Flow potential | Lower at similar conditions | Higher at similar conditions |
| Hose ends | Compatible -6AN fittings | Compatible -8AN fittings |
A larger fuel line can reduce flow restriction, but it does not automatically increase horsepower.
Fuel pump capacity, injector demand, fuel pressure, and the complete system design must be considered.

How to Install the EVIL ENERGY 6AN Fuel Line Kit
-
Relieve fuel system pressure and disconnect the battery before beginning work.
-
Measure the required hose lengths, accounting for routing and fitting insertion depth.
-
Select the appropriate straight, 45-degree, 90-degree, or 180-degree hose ends.
-
Cut the CPE braided hose squarely using a suitable cutting tool.
-
Inspect the hose liner and reinforcement for damage.
-
Assemble the reusable hose ends according to EVIL ENERGY’s instructions.
-
Connect the AN flare fittings to compatible mating connections.
-
Route the hose away from exhaust components, moving belts, and sharp edges.
-
Install the supplied separator clamps where appropriate.
-
Secure the hose and maintain the manufacturer’s minimum bend radius.
-
Pressure-test the completed hose assemblies and inspect for leaks before operating the vehicle.
AN vs. NPT Fittings
The included -6AN hose ends use 9/16-18 UNF threads and 37-degree AN flare sealing geometry.
AN and NPT connections are not interchangeable.
Do not force an AN fitting into an NPT port, and do not use PTFE tape on the AN flare sealing connection.
