Bosch 0445120289 Common Rail Fuel Injector 5268408 for Cummins ISDe

1. Product Overview

Brand new Bosch 0445120289 common rail fuel injector for Cummins ISDe (EU3) engines, Cummins OE number 5268408. The pairing is confirmed by a dealer matching table and a fuel-system catalogue, and the OE number itself is a genuine Cummins injector number sold through Cummins’ own store. Vehicle applications include Dongfeng and Yutong. Some market listings also group ISBe / QSB6.7 under this number; the catalogue-confirmed application is ISDe EU3, which is the fitment stated here. No Bosch exchange number could be confirmed for this injector, so none is shown. Note the consecutive numbers belong to a different maker: 0445120290 and 0445120291 are Yuchai-direction injectors — never carry this number’s Cummins data across to them.
