Setup and Installation
Proper installation is crucial for the performance and longevity of your fuel line kit. Follow these steps carefully:
1. Prepare the Hose
Before cutting, wrap the desired cut area of the hose tightly with electrical tape to prevent fraying of the nylon braid. Use a high-speed saw or an angle grinder with a cutting wheel for a clean cut. After cutting, ensure the inside of the hose is clear of any debris.

2. Assemble the Fittings
The fittings are designed for a secure connection. Unlike some lines that push and twist, these fittings require you to work the hose around and push it into the fitting. Apply a lubricant like petroleum jelly or light grease to the hose end to facilitate easier insertion into the adapter. Carefully thread the fitting onto the hose, ensuring the nylon braid does not fray excessively. Clean any frayed edges as needed.

3. Final Connection
Once the fittings are securely attached to the hose, connect the fuel line to your system. Ensure all connections are tight to prevent leaks. Double-check the working pressure and temperature of your system against the product specifications before operation.

Operating
After installation, perform a thorough check for any leaks before operating the vehicle. Start the engine and allow it to run for a few minutes, observing all connections for signs of fluid seepage. The hose is designed to handle specified working pressures and temperatures; ensure your system operates within these limits.
Maintenance
Regular inspection of your EVIL ENERGY fuel line kit is recommended to ensure continued safe operation. Periodically check the entire length of the hose and all fittings for:
- Signs of wear, abrasion, or damage to the outer nylon braid.
- Any signs of fluid leaks around the fittings or along the hose.
- Proper routing to avoid contact with hot engine components or sharp edges.
- Tightness of all connections.
Address any issues promptly to prevent potential hazards.
Troubleshooting
- Leaks at Fittings: Ensure fittings are properly assembled and tightened. Re-check the hose insertion into the fitting. If fraying occurred during assembly, it might compromise the seal. Disassemble, re-cut, and reassemble if necessary.
- Hose Damage: If the hose shows signs of cuts, abrasions, or excessive wear, it must be replaced immediately. Do not attempt to repair damaged sections of the hose.
- Fluid Compatibility Issues: While the hose is broadly compatible, ensure the specific fluid being used is within the recommended temperature and pressure ranges and does not react adversely with CPE rubber or nylon.
