## Discrepancy

(CAN) THE INDICATORS ON THE PUMP ASSEMBLIES ARE SHOWING A BYPASS CONDITION. WHEN EXAMINED THE FILTERS ARE CLEAN. THESE FILTERS CAN BE LEFT IN SERVICE UP TO 600 HR. BUT ARE NOW TRIPPING THE INDICATOR ANY WHERE FROM 5 TO 500 HRS. WITH THE TYPICAL TIME BEING LESS THAN 100 HRS. THERE WAS NO PROBLEM IN THIS AREA UNTIL JANUARY 2005.  ALL 3 INDICATOR ASSEMBLIES HAVE BEEN TESTED OK. THE TANKS AND TANK SCREENS HAVE BEEN INSPECTED AND FOUND CLEAN. THIS IS A KNOWN PROBLEM AS MFG ISSUED SB TFE731-73-3149 ON SEPT. 12, 2005 BUT AS YET THE NEW FILTERS ARE NOT AVAILABLE.
