It removes particulate contamination down to less than 4 microns and separates water to prevent injector and fuel system wear. This filter fits many on-highway trucks equipped with Cummins ISX11.9, ISX15.0, QSX11.9, or X15 engines, including Freightliner, Kenworth, Peterbilt, and Volvo models. A pre-installed fill plug simplifies pre-filling with clean fuel before installation.
