Moisture control is critical in modern diesel fuel systems, especially on engines that rely on high-pressure injection. The Baldwin Fuel Water Separator Filter is designed to remove water and fine contaminants before fuel reaches sensitive components like injectors and fuel pumps. Built as a primary filtration element, it uses specialized media that allows water to separate from the fuel stream so it can be collected and drained rather than carried downstream. With a compact 7.5-inch overall height and an integrated sealing design, this Baldwin PF9928 filter installs cleanly into compatible housings without disrupting fuel flow. It is commonly used on Kenworth and Peterbilt trucks equipped with Cummins ISL, ISX, and PACCAR MX and MX-13 engines, and serves as a direct replacement for PACCAR K371004 when maintaining OEM fuel system performance is a priority.
