Its job is to strip water and solid contaminants out of the fuel before it reaches the high‑pressure injection system. By keeping water out, it helps prevent injector tip erosion, pump wear, and fuel system corrosion. It is typically replaced as part of regular fuel‑filter service intervals, or whenever the water‑in‑fuel warning appears.
