Why Upgrade to a 22-Gallon System?
Early Mustangs came equipped with smaller 16-gallon tanks, which can limit driving range—especially in modified or high-performance builds. Upgrading to a 22-gallon tank paired with the correct filler neck offers:
- Fewer fuel stops on long drives
- Improved convenience for daily driving
- Better compatibility with performance engines that consume more fuel
- A clean, factory-style installation to the stock tail light panel with no visible external changes
Installation Tips
- Pair with a 1970-style fuel sending unit for optimal gauge accuracy
- Original sending units can be reused but may read “full” longer than expected
- Always install with a new filler hose and clamps to prevent leaks and ensure proper sealing
Complete Your Conversion
This fuel filler neck is a critical component for any 22-gallon tank upgrade, ensuring proper alignment, venting, and fuel delivery. For a complete solution, consider pairing it with a full conversion kit that includes the tank, sending unit, and installation hardware
