Fuel Gauge Sending Unit: Sub

Remove sub fuel gauge sending unit. Measure resistance between terminal No. 1 and 2 at fuel gauge sending unit connector while moving float up and down. See Fig 2. Resistance should increase as float lowers. See SUB FUEL GAUGE SENDING UNIT RESISTANCE table. Replace sub sending unit as necessary.
