P550219

FUEL FILTER, SPIN-ON

The Donaldson P550219 is a spin-on fuel filter designed to protect heavy-duty engine fuel systems by removing dirt, rust, and water droplets from diesel fuel. It uses cellulose filter media that captures particles as small as 14 microns at 50% efficiency, helping prevent premature wear on injectors and pumps. This filter screws onto a 13/16-18 UN threaded mounting stud and is commonly found on Mack A30 and B42 Renault VI E3 engines. Replace it at the manufacturer-recommended intervals to maintain fuel cleanliness and engine performance.
