Product Accuracy & Fitment Note Public supplier references connect Cummins 4327072 with ISLE 8.9 / ISL / QSL / QSC applications, while another public listing describes it as a Cummins ISL / QSL / ISC / QSC injector kit and includes many engine-control variants such as ISC CM2150, ISL CM2150, QSC8.3, QSL9 CM2250, QSL9 CM2350, QSL9 CM850, QSL9.3, and related L-series engines. Because these are market catalog references, the safe product-page wording is: “Fits selected Cummins QSL / QSL9 / ISL / ISC / QSC applications. Please verify by Engine Serial Number, CPL, old injector number, ECM type, fuel-system type, and injector photos before ordering.” Cummins official QSL9 information identifies the QSL9 marine engine as an 8.9 L inline 6-cylinder, turbocharged / aftercooled, high-pressure common rail diesel engine, with published marine power ratings around 290–410 hp, depending on configuration and rating class. Cummins also states that the QSL9 high-pressure common rail system maintains high injection pressure regardless of speed or load condition, supporting lower noise, lower vibration, and faster load acceptance.
