Product Detail Page Description 4326779 Fuel Injector Assembly for Cummins QSK23 / QSK Series Diesel Engine The 4326779 fuel injector is a Cummins diesel injector part number used in QSK-series heavy-duty engine aftermarket catalogues. Public supplier data lists 4326779 as a Cummins injector and shows cross-reference numbers including 4010158, 4087892, 4088426, 4088426PX, 4326779NX, and 4326779PX. Other remanufactured injector catalogues list 4010158, 4087892, 4088426, and 4326779 together with NX / PX / RX suffix variants. Important accuracy note: the strongest public cross-reference evidence for 4326779 connects it with Cummins QSK-series injectors, especially QSK45 in one remanufactured injector catalogue. Some marketplace listings market 4326779 / 4928346 / 4928349 for QSK23 excavator applications, but those same listings may contain inconsistent application text. Therefore, for a QSK23 product page, 4326779 must be verified by engine serial number, CPL, old injector number, ECM/fuel-system type, injector photos, and equipment model before shipment. The Cummins QSK23 is a 23 L inline 6-cylinder diesel engine family. Cummins lists QSK23 well-servicing ratings at 760–950 hp / 567–708 kW, and QSK23 G-Drive engines use the Cummins High Pressure Injection HPI-PT full-authority electronic fuel system.
