Installation Instructions
- Ensure the vehicle's engine is off and the area around the fuel filler neck is clean and free of debris.
- Remove the old fuel cap by twisting it counter-clockwise until it loosens and can be pulled off.
- Align the new Stant Pre-Release Fuel Cap with the fuel filler neck.
- Twist the cap clockwise until you hear several clicks or feel firm resistance. This indicates the cap is properly sealed.
- Verify the cap is securely fastened and does not spin freely.
Operating the Fuel Cap
To open the fuel tank, twist the Stant Pre-Release Fuel Cap counter-clockwise. The pre-release mechanism is designed to vent any built-up pressure in the fuel tank before the cap is fully removed, enhancing safety. Continue twisting until the cap is loose and can be removed. To close, follow the installation steps.
Maintenance
Regular maintenance ensures the longevity and proper function of your fuel cap:
- Cleaning: Periodically wipe the cap and the fuel filler neck area with a clean, damp cloth to remove dirt and grime.
- Seal Inspection: Inspect the rubber gasket or O-ring on the underside of the cap for cracks, tears, or signs of wear. A damaged seal can lead to fuel vapor leaks and trigger a "Check Engine" light.
- Proper Storage: If the cap is removed for an extended period, store it in a clean, dry place to prevent contamination.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| "Check Engine" Light On | Fuel cap not tightened properly or seal is damaged. | Re-tighten the cap until it clicks. Inspect the seal for damage; replace cap if necessary. |
| Difficulty twisting cap | Dirt or debris in the filler neck threads. | Clean the filler neck threads and the cap's threads. |
| Fuel odor present | Cap not sealed correctly or damaged. | Ensure cap is fully tightened. Check for seal damage. If odor persists, seek professional inspection. |
