Fuel Tank Sending Unit
- With sending unit removed from tank, clip float arm to empty stop and turn ignition to "ON" position. After two minutes, gauge should read "EMPTY", plus one pointer width or minus two pointer widths.
- Move and clip float arm to full stop. Gauge should read "FULL", plus two pointer widths, minus one pointer width.
- If gauge does not meet specifications, check wiring, connections and fuel gauge (using tester C-3846 or known good sending unit).
- If gauge is bad, replace. If gauge is good, replace sending unit.
