Our 118mm / 4.65" family of spin-on fuel assemblies features one head option and a range of filter lengths with various efficiency ratings to protect your fuel system and assist with water separation. Choose the media type and configuration that’s best for your application. Whether you are looking for high-efficiency particulate removal or fuel and water separation, the options are available for your needs.
For water maintenance flexibility, Donaldson fuel filter water separators have a connection that can accommodate multiple drain valve types, as well as a water collection bowl. The clear water collection bowl (80 mL / 2.7 oz capacity) is a separate component that can be added on for easy, visual water inspection and maintenance. All fuel filter water separators ship with a standard Twist&Drain™ valve. A variety of other Twist&Drain valves types are available so you can configure the exact system needed.
