Product Detail Page Description
4010025 Fuel Injector Assembly for Cummins QSK23 / QSK Series Diesel Engine
The 4010025 fuel injector is a heavy-duty diesel injector / injector nozzle assembly used in Cummins QSK series engine applications. Public aftermarket catalogues commonly list 4010025 together with 4001813, 4087893, 4088427, and 4326780. Some catalogues connect this injector group with QSK19 / QSK23 / QSK60, while other listings mainly show QSK45 / QSK60 applications. Because of this catalogue overlap, 4010025 should not be ordered by part number alone. Final confirmation must be made by engine serial number, CPL, old injector number, ECM/fuel-system type, equipment model, and injector photos.
Cummins lists the QSK23 as a 23 L inline 6-cylinder engine family with 760–950 hp / 567–708 kW power range and High Pressure Injection HPI fuel system. Cummins also states that the QSK23 high-pressure injection system works up to 29,000 psi, and QSK23 G-Drive versions use an HPI-PT full-authority electronic fuel system.
