Problem -
INTERMITTENT OPERATION OF FUEL GAUGE
The one or more of the following symptoms may be experienced:
a. Fuel gauge reads zero regardless of fuel level in tank.
b. Gauge shows a constant reading with various levels of fuel level in tank.
c. The fuel gauge consistently indicates inaccurate fuel levels.
Cause
Ultra low Sulphur fuel contamination.
Action
Where a complaint consistent with any of the above symptoms is confirmed, use the procedure below to ensure correct operation of the fuel gauge sender unit. SYMPTOMS ‘a’ and 'b'
•Replace the sender unit. Refer to Workshop Manual, part number LRL0350 (3rd edition), Instruments, Sender unit - fuel tank gauge, repair number 88.25.32.
SYMPTOM ‘c’
1. Remove the fuel pump assembly. Refer to Workshop Manual, part number LRL0350 (3 rd edition), Pump - fuel, repair number 19.45.08.
2. Inspect the pump assembly for external damage, e.g: distorted sender unit float arm.
3. If no visual defects can be seen, disconnect the 2 fuel gauge sender connectors from the top of the pump assembly, (arrowed in illustration) and connect to an electrical test meter.
4. Place the pump assembly upright on a flat level surface.
5. Measure the distance from the surface to the rest position of the end of the float arm, dimension ‘A’ in illustration.
6. With the float arm still in the rest position, note the resistance at the sender connectors. Refer to table for correct dimension and resistance.
7. With the meter still connected, raise the float arm slowly to its highest position, and monitor the meter for a smooth fall in resistance, if the meter goes open circuit at any point in the float arm travel, replace the sender unit.
8. With the float arm at dimension ‘B’ in the illustration, repeat float height and resistance measurements. Refer to table for correct dimension and resistance. Minor adjustments can be made to the position of the float by carefully bending the float arm.
9. If the measured resistance remains outside the specified range, replace the sender unit. Refer to Workshop Manual, part number LRL0350 (3rd edition), Instruments, Sender unit - fuel tank gauge, repair number 88.25.32.
10. Refit the fuel pump assembly to the tank using a new sealing ring ESR3806.
