ISSUE:
The fuel gauge may operate erratically and/or have inaccurate readings. This may be caused by the sensing float being positioned at the extreme aft of
the fuel tank.
ACTION:
Replace the fuel pump and sender assembly with a revised pump and sender. The revised pump and sender has a repositioned sensor assembly to bring
the float assembly closer to the center of the fuel tank. This should reduce the possibility of inaccurate and erratic readings. Refer to the following
Service Procedure for details.
SERVICE PROCEDURE
1.
Remove the fuel tank as outlined in Section 310-01 in the 1997 Expedition Workshop Manual.
2.
Remove the fuel pump and sender assembly as outlined in Section 310-01 of the Workshop Manual.
NOTE:
THERE IS NO NEED TO REMOVE THE SENDING UNIT FROM THE REMOVED PUMP. THE REPLACEMENT PUMP HAS A NEW
SENDER FITTED ALREADY. THIS SENDER IS ORIENTED DIFFERENTLY FROM THE REMOVED PART. THIS WILL PUT THE FLOAT
CLOSER TO THE CENTER OF THE TANK.
3.
Remove the pressure transducer from the removed pump and install it onto the new pump. Make sure the electrical connection is made.
4.
Using a new green seal (included with the pump), reinstall the pump and sender into the tank as outlined in Section 310-01 of the Workshop
Manual.
5.
Reinstall the fuel tank as outlined in Section 310-01 of the Workshop Manual.
NOTE:
WHEN THE BATTERY IS DISCONNECTED AND RECONNECTED, SOME ABNORMAL DRIVE SYMPTOMS MAY OCCUR WHILE THE
VEHICLE RELEARNS ITS ADAPTIVE STRATEGY. THE VEHICLE MAY NEED TO BE DRIVEN 16 km (10 MILES) OR MORE TO
RELEARN THE STRATEGY.
