Agility Autoparts Fuel Tank Sending Unit P/N:4017021
Keep an accurate fuel gauge reading with the Agility Auto Parts Fuel Tank Sending Unit (MPN 4017142), a drop-in replacement for the 1977-1984 Buick Electra. A fuel tank sending unit uses a float and variable resistance to track the fuel level in the tank and send that signal to the dash-mounted fuel gauge — when the original sender fails, the gauge can read erratically, stick, or stop moving, and replacing a faulty sender is what this unit is designed to do.
Agility Auto Parts is a North American company with distribution warehouses in Canada and the United States for timely bulk delivery. Confirm the fitment for your Electra, then bolt in the correct-application sender.
