Caterpillar 2998229 Fuel Filter Assembly

The Caterpillar 2998229 is an Ultra High Efficiency (UHE) spin-on fuel filter engineered to meet the stringent fuel cleanliness requirements of modern Caterpillar diesel engines. It utilizes advanced filter media capable of removing particulate contaminants and water with efficiency exceeding 99%, protecting high-pressure common rail fuel systems and unit injectors from premature wear. Constructed with a strong one-piece can design and a non-metallic center tube, the filter minimizes potential leak paths and eliminates metallic contamination risk. The filter features a M12 x 1.5 thread interface, 140 mm overall height, and 77.8 mm outer diameter. Flow direction is outside-in. It serves as a direct replacement for Caterpillar OEM part numbers 299-8229 and 2998229, and cross-references to Perkins 2656F843, Fleetguard FF261, Baldwin BF7990, Donaldson P502504, and Wix 33076 among others.
