Cutlass V6-191 3.1L VIN M SFI (1998)
Fuel Pump Pickup Filter: Description and Operation
A woven plastic strainer (3), is located on the lower end of the fuel sender. This filter prevents dirt from entering the fuel line and also stops water unless
the filter becomes completely submerged in water. This filter is self cleaning and normally requires no maintenance. Fuel stoppage at this point indicates
that the fuel tank contains an abnormal amount of sediment or water. Therefore, should this occur, the fuel tank should be removed and thoroughly
cleaned and the tank filter replaced.
