Description
Fleetguard FS19732 spin-on fuel/water separator for Cummins QSB, QSC, and QSL off-highway diesel engines. Uses StrataPore media to deliver 98.7% filtration efficiency at 25 microns (SAE J1985) and 95% removal of free and emulsified water — the protection spec Cummins requires for QS-family fuel systems on construction, ag, and industrial equipment. Replaces Cummins 3973233, Baldwin BF1385-SPS, and Donaldson P550848 — the OEM service element for Cummins QSB6.7, QSC8.3, and QSL9 powered machines.
