Auxiliary Fuel Tank Filler Neck, 1977 Ford Bronco SKU: 9723

1977 Ford Bronco Front Auxiliary Fuel Tank Filler Neck

If you're restoring a 1977 Bronco, you know Ford threw a few curveballs that year—like the switch to fuel doors instead of the old-school exposed gas caps. This Front Auxiliary Fuel Tank Filler Neck is made just like the factory original and is built to fit that one-year-only setup.

This steel filler neck connects the fuel door bucket to the rubber filler hose, which then runs to the auxiliary tank tucked under the driver-side floor. It’s an exact-fit piece for the 1977 Ford Bronco and works only with the front auxiliary tank—not the rear main.

• Fits: 1977 Ford Bronco

• Tank Position: Front auxiliary (driver side, under floor)
