Water is a leading cause of wear in high-pressure fuel systems, so this Freightliner 03-40538-006 unit removes moisture and fine particulates before they reach sensitive injection components. A built-in water-in-fuel sensor signals the driver when contamination collects in the bowl, allowing it to be drained before injector performance is affected. For service work, a top-mounted manual priming pump makes it easier to clear air from the system after filter changes. That combination of early warning and easier priming helps technicians keep fuel-related issues from turning into repeat downtime.
