Overview
Our 108mm / 4.25" family of spin-on fuel assemblies features two head options. The heads have two inlet ports and two outlet ports. Two ports are shipped plugged. This allows for flexible mounting configurations. There are a couple of filter lengths with media options to protect your fuel system and assist with water separation.
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 options are available so you can configure the exact system needed.
