## Discrepancy

WHILE TROUBLESHOOTING AN INACCURATE FUEL QUANTITY PROBLEM, DISCOVERED THE PLASTIC FLOAT ON THE END OF THE FUEL SENDER ARM HAD COME OFF AND WAS FLOATING IN THE FUEL TANK.  THE FLOAT IS RETAINED BY A WASHER AND CRIMPING OF THE END OF THE SHAFT.  THE CRIMP WAS INADEQUATE WHICH ALLOWED WASHER AND FLOAT TO COME OFF THE SHAFT RESULTING IN AN ERRONEOUS QUANTITY READING.  SUBMITTER RECOMMENDS A MORE POSITIVE METHOD OF FLOAT RETENTION BE UTILIZED DURING MANUFACTURE.
