6. Installation Instructions
Follow these steps for proper assembly and installation of the 6AN fuel line kit:
6.1. Hose Preparation and Cutting
- Measure the required length of the hose carefully.
- Wrap the cutting area of the hose tightly with electrical tape to prevent fraying of the nylon braid.
- Using a sharp hose cutter or fine-tooth saw, cut the hose squarely through the taped section. Ensure a clean, straight cut.
- Remove the tape and clean any debris from the cut end.
6.2. Fitting Assembly
- Unscrew the fitting's socket (outer nut) from the nipple (inner part).
- Insert the cut end of the hose into the socket. Push firmly until the hose bottoms out against the threads inside the socket.
- Apply a small amount of AN fitting lubricant or clean engine oil to the nipple threads.
- Carefully thread the nipple into the hose and socket assembly. Ensure the hose does not back out of the socket.
- Tighten the nipple into the socket using two AN wrenches (one to hold the socket, one to turn the nipple) until snug. Do not overtighten.
- Inspect the assembly for any exposed braid or improper seating.
6.3. Hose Separator Clamp Installation
- Position the hose separator clamps along the hose run where needed to maintain proper spacing and prevent rubbing.
- Secure the clamps using the provided hardware.

7. Operating Considerations
After installation, perform the following checks before operating the vehicle:
- Leak Check: With the engine off, cycle the ignition key to pressurize the fuel system (if applicable) and visually inspect all connections for any signs of leaks. For oil or coolant lines, start the engine and monitor for leaks.
- Clearance Check: Ensure the hose and fittings do not rub against any moving parts, sharp edges, or hot components. Adjust routing as necessary.
- Secure Mounting: Confirm all hose separator clamps and mounting points are secure.
During initial operation, periodically check the lines for leaks or signs of wear, especially after the first few driving cycles.
8. Maintenance
Regular maintenance helps ensure the longevity and safe operation of your fuel line kit:
- Visual Inspection: Periodically inspect the entire length of the hose and all fittings for signs of wear, cracks, abrasions, or leaks. Pay close attention to areas near heat sources or moving parts.
- Cleanliness: Keep the hose and fittings clean from dirt, grime, and corrosive substances. Use a mild detergent and water if cleaning is necessary.
- Tightness Check: Occasionally check the tightness of the AN fittings. Do not overtighten.
- Hose Routing: Ensure the hose remains properly routed and secured by the separator clamps. Adjust if any shifting has occurred.
9. Troubleshooting
If you encounter issues with your EVIL ENERGY 6AN Fuel Line Kit, consider the following:
9.1. Leaks at Fittings
- Cause: Improper assembly, insufficient tightening, damaged threads, or incorrect hose cut.
- Solution: Disassemble the fitting, inspect threads for damage, ensure the hose is fully seated in the socket, re-lubricate threads, and reassemble, tightening to the recommended torque (snug, not excessive). If threads are damaged, replace the fitting.
9.2. Hose Fraying
- Cause: Improper cutting technique, rubbing against other components.
- Solution: Ensure proper cutting technique with tape. If fraying occurs during use, re-route the hose to prevent contact with abrasive surfaces or sharp edges. Use hose separator clamps to maintain clearance.
9.3. Restricted Flow
- Cause: Kinked hose, debris inside the line.
- Solution: Inspect the hose for kinks and re-route if necessary, ensuring the minimum bend radius is not exceeded. If debris is suspected, disconnect and flush the line.
