Bulletin: 89-6C-8

Date: Jan., '89

Ref. No.: 89-037-6C

Corp. Ref. No.: 806303R


SUBJECT:
FUEL PUMP STRAINER REPLACEMENT (ALSO COMMONLY CALLED AN IN-TANK FILTER OR SOCK)


MODELS AFFECTED:
ALL 1984 THROUGH 1989 BUICK MODELS EQUIPPED WITH IN-TANK ELECTRIC FUEL PUMPS


There have been comments of vehicles experiencing multiple fuel pump failures, where it has been determined that the failure of the replacement pumps was the direct result of transferring a contaminated strainer from the original pump. Sometimes the contamination is on the inside of the strainer and not readily visible.

In order to eliminate the possibility of damage or diminishing longevity of a service replacement fuel pump, it is always necessary to replace the fuel strainer at the same time as replacing the pump.
