The Donaldson P551103 is a spin-on fuel filter and water separator designed for diesel engines. It uses Twist&Drain™ technology for easy, tool-free draining of separated water. The filter captures 99% of particles as small as 10 microns and removes 95% of emulsified water, helping prevent injector wear and fuel system corrosion. This filter serves as a replacement for Cummins 3406889 and is intended for heavy-duty on-highway and off-road applications, but is not for marine use.
