P552855
This is a spin‑on fuel water separator filter for diesel engines. It traps water and solid contaminants from the fuel before they reach the engine, helping protect injectors, pumps, and other fuel‑system components. Replacing the filter at recommended service intervals (or when a water‑in‑fuel warning appears) prevents engine damage and keeps your truck running reliably.
