2123657 Pump As-W/Filter Fits Caterpillar Models

One New Aftermarket Replacement Fuel Priming Pump with Water Separator for Caterpillar (Cat) Equipment

This aftermarket replacement fuel priming pump assembly with integrated water separator (Cat part 212-3657 / 2123657) services the primary fuel system on a wide range of Caterpillar construction and earthmoving machines. The pump removes air from the fuel system and separates water contamination before fuel reaches the engine, protecting Cat C-series and 3126B diesel engines from fuel-related damage.
