Fuel Gauge Sender: Testing and Inspection

Fuel Level Gauge Inspection

Main Fuel Level Gauge
- Check that resistance between terminals [a] and [b] of main fuel level gauge changes depending on float (2) position.
- Check resistance between terminals [a] and [b] at each float position in the following.
If the measured value is out of specification, replace fuel pump (1).







Sub Fuel Level Gauge
- Check fuel pump assembly for damage.
- Check that resistance between terminals [a] and [b] of sub fuel level gauge changes depending on float (1) position.
- Check resistance between terminals [a] and [b] at each float position in the following.
If the measured value is out of specification, replace sub fuel level gauge.
