Protect your diesel fuel system with the Baldwin BF1259 Fuel/Water Separator. Designed for heavy-duty equipment and on-highway applications, this spin-on filter helps separate water and contaminants from diesel fuel before they reach sensitive fuel-system components.
The BF1259 uses a 10-micron filter element and features a durable spin-on design for convenient filter replacement. Its 1"-14 mounting thread and approximately 3-11/16" outside diameter by 9-17/32" height make it suitable for a range of diesel-powered trucks, engines, tractors, and construction equipment when the specified dimensions and application requirements match.
The filter includes a standpipe and sealing components. Baldwin application information identifies use with select Caterpillar and Cummins engines, Euclid rear dumps, Kenworth and Volvo trucks, and Versatile tractors. Always verify the equipment manufacturer's application and filter specifications before ordering.
