This is a new, genuine Kubota fuel injector, part number 1J419-53002. Kubota sells it as a nozzle holder assembly (ASSY HOLDER NOZZLE): the complete mechanical injector with its nozzle. It fits the Kubota V3800DI-T, the 3.8 liter four-cylinder direct-injection turbo diesel, in Kubota’s 1J419 engine series. Kubota engine dealers list the complete 1J419 engines as the V3800DI-T-E3BG, the generator-drive build. It is Kubota’s replacement for 1J419-53000. The engine takes four.

The V3800 direct-injection engines have used more than one nozzle holder, so this is a part to order by number. Injectors are replaced for hard starting, smoke, a miss under load or fuel knock, and a pop test for opening pressure and spray pattern settles whether the injector is at fault. On a generator set, check the fuel supply, the filters and the injection pump before you replace a set.
