FF5319, Secondary Fuel Filter, Spin-On, Compatible with Caterpillar

The FF5319 Fuel Filter is a high‑efficiency spin‑on fuel filter designed to protect the fuel system of heavy‑duty diesel engines, especially Caterpillar applications. This filter traps contaminants and microscopic particles in diesel fuel, helping prevent injector wear, maintain smooth engine operation, and extend service life.

Made by Fleetguard (Cummins Filtration) or available as equivalent replacement brands, this fuel filter meets or exceeds OEM filtration performance, offering reliable protection in demanding conditions.

Compatible with many Cat engines such as 3406, C10, C11, C12, C13, C15, C16 and others where Caterpillar part 1R0749 is used, the FF5319 performs well across trucks, heavy equipment, and diesel machines running Cat power plants.
