P550746 Filter-Fuel Fits Donaldson Models

One New Aftermarket Replacement Fuel Filter/Water Separator for Donaldson-Equipped Diesel Engines and Equipment

The Donaldson P550746 is a spin-on fuel filter/water separator designed to protect diesel fuel systems by removing free water, emulsified water, and particulate contaminants before they reach the engine. This filter is used as the primary fuel/water separator on a wide range of heavy-duty diesel engines and equipment including Volvo trucks, Caterpillar machines, Atlas Copco generators and compressors, Generac generator sets, and other equipment using compatible Donaldson filter housings. Keeping this filter serviced helps prevent injector wear, corrosion, and fuel-related engine damage.
