P550849

FUEL FILTER, WATER SEPARATOR CARTRIDGE

The Donaldson P550849 is a fuel filter and water separator cartridge designed for diesel engines. It removes solid contaminants and separates emulsified water from diesel fuel to protect fuel injectors, pumps, and other sensitive components from wear and corrosion. Replacing this cartridge at the recommended intervals ensures clean fuel delivery, maintains engine efficiency, and helps prevent costly fuel system repairs. It is commonly used in heavy-duty trucks, construction equipment, and fleet vehicles equipped with DAVCO fuel processor systems or engines that call for the Caterpillar 3700572 specification.
