This fuel filter element removes particulate and water from the fuel supply before it reaches the injection system. It sits in the filter head on the feed line between the tank and the high-pressure pump. A clogged element restricts fuel flow, causing the engine to lose power under load and potentially allowing debris to reach the injection components. As an original-manufacturer component, the filter body matches the sealing surface geometry of the housing, ensuring the bypass valve seats correctly and no unfiltered fuel bypasses the element. Replace the filter at the interval specified in the machine's service schedule.
