Product Introduction
The 4238522 replacement fuel water separator is intended for compatible diesel fuel systems, combining fuel filtration and water separation functions. The original part reference 423-8522 identifies a spin-on fuel filter and water separator.
Fuel water separators help capture contaminants and separate water from diesel fuel before it reaches downstream fuel system components. Regular inspection, water drainage and filter replacement should follow the equipment manufacturer’s maintenance instructions.
The spin-on configuration allows the filter unit to be replaced during scheduled servicing. Before ordering, confirm the filter dimensions, mounting thread, sealing gasket and any bowl, drain or sensor connections required by your installation.
