3. Setup and Installation
Professional installation is highly recommended for this PTFE fuel line kit. Proper installation is crucial for safety and optimal performance. The hose is relatively rigid and cannot be bent or folded sharply. Always ensure a minimum bend radius of 3.5 inches (88.9mm).
General Installation Guidelines:
- Preparation: Before cutting, use electrical tape around the hose at the desired cut point to prevent fraying of the nylon braid.
- Cutting: Use a sharp tool, such as a cut-off wheel, to make a clean cut. Avoid using scissors or pliers that may deform the hose or fray the braid.
- Hose Recovery: After cutting, the PTFE hose may deform. Use a specialized tool to recover the cut end to its original shape before installing fittings. Ensure no braided wire is caught between the hose and the ferrule during assembly.
- Fitting Assembly: Lubricate the PTFE hose and fitting threads. Insert the PTFE hose into the fitting socket. Turn the hose clockwise into the socket until it bottoms out. Then, insert the nipple into the hose and push it through the socket while turning the nipple clockwise. Ensure the nipple threads engage properly with the socket threads. Tighten securely.
- Inspection: After assembly, thoroughly inspect all connections for any signs of leaks or improper seating.

4. Operating
Once properly installed, the EVIL ENERGY 6AN PTFE Fuel Line Kit operates as a critical component in your vehicle's fuel, lubricant, or coolant system. It is designed for continuous operation within its specified pressure and temperature ranges. Regular checks of the system are recommended to ensure continued integrity.
5. Maintenance
To ensure the longevity and reliable performance of your EVIL ENERGY PTFE Fuel Line Kit, consider the following maintenance practices:
- Regular Inspection: Periodically inspect the entire fuel line system for any signs of wear, abrasion, cuts, or leaks. Pay close attention to connection points and areas where the hose may rub against other components.
- Cleaning: Keep the exterior of the hose clean from dirt, debris, and corrosive substances. Use appropriate automotive cleaning products.
- Avoid Excessive Bending: Ensure the hose maintains its minimum bend radius during operation and storage to prevent internal damage.
- Check Fittings: Verify that all AN fittings remain tight and secure. Overtightening can damage threads, while undertightening can lead to leaks.
6. Troubleshooting
If you encounter issues with your EVIL ENERGY 6AN PTFE Fuel Line Kit, refer to the following common problems and solutions:
Common Issues:
- Leaks at Fittings:
- Cause: Improper assembly, braided wire caught in the ferrule, or insufficient tightening.
- Solution: Disassemble the fitting, ensure no braided wires are between the hose and ferrule, lubricate threads, and reassemble carefully, ensuring the hose is fully seated and the fitting is tightened correctly.
- Hose Bursting/Damage:
- Cause: Exceeding maximum pressure, excessive bending, or external abrasion.
- Solution: Verify system pressure is within the hose's limits. Ensure the hose is routed to avoid sharp bends and contact with abrasive surfaces. Replace damaged sections immediately.
- Hose Appears Undersized:
- Cause: Misunderstanding of AN sizing conventions or incorrect product selection.
- Solution: Always refer to the actual inner diameter (ID) and outer diameter (OD) specifications provided in the product details and compare them to your application requirements. The 6AN hose has an ID of 5/16" (0.31 inch).
