John Deere MIU803127 Final Fuel Filter Assembly

The John Deere MIU803127 is a genuine OEM spin-on final fuel filter designed for secondary filtration in diesel fuel systems. It utilizes a cellulose media element housed in a steel canister with a plastic base to remove fine particulates and water from fuel before it reaches the high-pressure injection pump and injectors. This filter serves as the secondary (final) stage in a two-filter fuel system configuration, typically paired with a primary fuel filter water separator. It is engineered to meet OEM flow restriction and filtration efficiency standards for Yanmar 3TNV series engines used in John Deere 3E, 3R, 4M, and 4R series compact utility tractors, as well as 1500 series TerrainCut front mowers and Z900 series ZTrak mowers. The filter features a standard M16 x 1.5 thread interface and includes a sealing gasket for leak-free installation.
