This fuel filter with integrated water separator removes particulate and water from the fuel supply before it reaches the high-pressure injection system. It mounts in the fuel line between the tank and the primary lift pump, where its separator element coalesces water droplets and directs them to the collection bowl. A clogged filter or a water-saturated separator restricts flow, causing the engine to lose power or stall under load. The filter housing threads onto the mounting head with the specified torque; the separator bowl must be drained periodically according to the machine's service schedule.
