Complete Fuel System Renewal — 4-Injector Set for Kubota D1503, V2003 & V2403 Engines

One part number, four engine families, ten equipment models. The 16419-53900 is one of the most versatile Kubota injectors available — covering the D1503, D1503-T, V2003, and V2403 across a wide range of Kubota tractors, loaders, and utility equipment. When injectors wear on these engines, power drops under load, fuel consumption climbs, and the smooth operation Kubota owners expect disappears. This matched set of 4 OEM-equivalent injectors restores factory fuel delivery across all cylinders in a single service.
