JCB 40302054 Water Separator Assembly

The JCB 40/302054 water separator assembly is a fuel system component designed to remove water and contaminants from diesel fuel before it reaches the injection system. It features a sediment bowl and filter element housing constructed for high-pressure common rail and mechanical injection systems used in JCB backhoe loaders and excavators. OEM cross-references include 333/Y6130 and 320/A7291. This assembly mounts on the engine fuel filter bracket and incorporates a drain valve for periodic water removal. It is a direct replacement for the factory-installed unit on specified JCB models. Verify machine serial number for exact fitment as part numbers may vary across production years.
