Installation (Setup)
Installation of the fuel tank filler neck typically involves removing the old component and installing the new one. While this product is designed for easy installation, professional installation is recommended if you are not familiar with automotive fuel system repairs.
General Installation Steps:
- Preparation: Park the vehicle on a level surface, engage the parking brake, and disconnect the negative battery terminal. Ensure the fuel tank is as empty as possible.
- Access: Depending on your vehicle, you may need to remove the rear wheel, fender liner, or other components to access the fuel filler neck.
- Disconnect Hoses: Carefully disconnect the main fuel filler hose and any vent hoses from the old filler neck. Be prepared for residual fuel to escape.
- Remove Old Filler Neck: Unbolt or unclip the old filler neck from its mounting points on the vehicle body and fuel tank.
- Install New Filler Neck: Position the Spectra Premium FN1005 filler neck and secure it to the mounting points. Ensure all connections are tight and properly seated.
- Reconnect Hoses: Reattach the main fuel filler hose and vent hoses to the new filler neck. Use new clamps if necessary to ensure a leak-free seal.
- Reassemble: Reinstall any removed vehicle components (fender liner, wheel, etc.).
- Final Check: Reconnect the battery. Add a small amount of fuel and check for any leaks before fully refueling. Start the vehicle and check for any warning lights.

Operation
Once properly installed, the Spectra Premium FN1005 Fuel Tank Filler Neck operates passively as part of your vehicle's fuel system. Its primary function is to provide a secure and leak-free conduit for refueling and to maintain the integrity of the evaporative emissions system.
- Ensure your Original Equipment (OE) fuel cap is used and properly tightened after each refueling to prevent EVAP system issues and check engine light activation.
- The dual coating provides enhanced corrosion protection, contributing to long-term reliability.
Maintenance
The Spectra Premium FN1005 Fuel Tank Filler Neck requires minimal maintenance. Regular inspection is recommended to ensure continued performance.
- Periodically inspect the filler neck for any signs of damage, corrosion, or leaks, especially around the hose connections and mounting points.
- Check the condition of the fuel filler hose and vent hoses connected to the filler neck. Replace them if they show signs of cracking, hardening, or deterioration.
- Ensure the fuel cap seals properly. A faulty fuel cap can lead to evaporative emissions system problems.
Troubleshooting
If you encounter issues after installing the Spectra Premium FN1005 Fuel Tank Filler Neck, consider the following:
- Fuel Leaks: If you detect a fuel smell or visible leaks, immediately cease vehicle operation and inspect all hose connections and mounting points for proper seating and tightness. Ensure hose clamps are secure.
- Check Engine Light (EVAP System): A check engine light related to the EVAP system (e.g., P0440, P0442, P0455) can indicate a leak in the fuel system. Double-check that the fuel cap is tightened correctly and that all hoses connected to the filler neck are sealed. The FN1005 is leak-tested, but installation errors or issues with other components can cause problems.
- Difficulty Refueling: If fuel flow is restricted or the pump repeatedly clicks off, ensure there are no kinks in the filler hose or vent hoses.
If troubleshooting steps do not resolve the issue, consult a qualified automotive technician.
