It is designed to remove virtually all free water and a significant portion of emulsified water from diesel fuel before it reaches the high-pressure injection system. By capturing water and fine contaminants that can erode injectors, this filter helps prevent power loss, poor fuel economy, and expensive injector failures. It is typically replaced at regular service intervals or whenever the fuel system warning indicates excessive water accumulation.
