Engineered specifically for the Cummins 15-liter platform, the 4088723 diesel fuel injector is a direct match for QSK15, QSKX15, QSX15, ISX15 and X15 engines. Public listings place 4088723 in the same product group as 1481827, 1846351, 4954646, 4954648, 570016, 1499714 and 1521977 for ISX15, QSX15 and X15 applications, with QSKX15 confirmed in the specification data. This engine-focused fit ensures the injector aligns with the fuel system, delivery pressure and mounting requirements of these heavy-duty units.
The QSX15 is a 15-liter heavy-duty diesel engine rated at 450–675 hp with 1650–2050 lb-ft of torque, while QSX15 generator sets carry prime ratings of 291–455 kW and standby ratings of 320–500 kW. Within these demanding duty cycles, the 4088723 provides precision fuel delivery and fine atomization to support stable idle, power recovery and reduced smoke potential across trucks, excavators, generator sets, mining and oilfield machinery.
Backed by a broad cross-reference range and global aftermarket availability, this injector suits distributors, repair shops, fleet operators and engine rebuilders. Before installation, confirm the original injector number, engine serial number, CPL, fuel-system type and machine model. Install clean, replace all required seals, apply correct torque, bleed the system, check for leakage and test under load for reliable performance.
