Detailed Product Description

The Baldwin BF46129 fuel filter is engineered to meet the filtration requirements of heavy-duty diesel engines, specifically those found in Freightliner, Kenworth, Peterbilt, and Volvo trucks powered by Cummins ISX engines. Its dimensions, including a height of 8 27/32 inches and an outside diameter of 4 23/32 inches, ensure proper fitment and compatibility. The filter features a pre-installed fill plug, which should be removed after pre-filling to ensure optimal fuel flow. The attached gasket and O-ring provide a secure seal to prevent leaks and maintain system pressure. This filter replaces several OEM part numbers, making it a suitable aftermarket option for maintaining fuel cleanliness and engine efficiency.
