Fill the tank and see if you get a full reading. If not, then you need to
check the connections, ground for the sensor, and the voltage from the gauge
voltage regulator. If all the lectrical checks out, you can remove the gauge
itself and adjust the zero point mechanically. There is an adjustment
inside.

Hi gang! I recently installed new fuel tank and sending unit and with 12
gallons approximately of fuel its showing about half a tank. Is there some
adjustment I can do to calibrate it?
