Early Bronco Auxiliary Fuel Tank with Pre-Installed Sending Unit

Built to match the original design, this Early Bronco front auxiliary gas tank with pre-installed sending unit is the OE-style solution for reliable auxiliary fuel storage. Made from high-quality polyethylene, this 8-gallon tank is a direct replica of the factory side fuel tank used in 1970 and later Broncos. Unlike typical aftermarket tanks, this unit uses a lock ring and O-ring setup—just like the original—for a secure, leak-resistant seal.

Best of all, the sending unit comes pre-installed, eliminating the guesswork and potential for over- or under-tightening screws. It also features correct overfill and EVAP vent fittings to suit later-model emissions setups while remaining fully adaptable to earlier trucks by simply capping the unused ports.


  • Fits All Early Broncos: Designed to fit 1966–77 Ford Bronco—matches the OE tank used from 1970 onward.

  • 8-Gallon Capacity: Compact auxiliary tank ideal for trail runs, backups, or long hauls.

  • Pre-Installed Sending Unit: Ready to go out of the box—no struggling with over or under-tightening.

  • OE-Style Construction: Uses lock ring and O-ring for a correct, leak-proof fit—just like the original.

  • Includes Vent Hose Fittings: Features overfill and EVAP vent ports found on later-model Broncos; earlier models can cap unused fittings as needed.


This OE-style auxiliary tank brings your Bronco back to factory spec - complete with pre-installed sending unit and proper vent fittings for a no-leak install.
