We offer a full line of Twist&Drain™ accessories, which include water collection bowls, valves, replacement seals, and a Water-in-Fuel Sensor LED Display Kit. All Donaldson Twist&Drain style 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 (80mL / 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.
Water is one of the most harmful contaminants found in fuel. Donaldson's water-in-fuel sensor and display kit is designed to give a visual warning for when separated water is present in the filter and needs to be drained. The kit contains a drain valve with electrical plug, wiring loom and a dash mount LED display.
If seals show signs of wear or deterioration they should be replaced. The placement of the seals are between the threaded connections of the filter, water collection bowl, and Twist&Drain valve. When purchasing a water collection bowl or a Twist&Drain valve, one seal will be included.
