Product Accuracy & Fitment Note Public supplier references connect Cummins 4359204 with ISLE 8.9 / ISL / QSL / QSC applications, and other public listings specify QSL9.3 / QSC8.3 / CM2880 engine applications. Some listings also use the compact alternate search number C4359204. Because these are supplier catalog references rather than official Cummins QuickServe fitment records, the safest product-page wording is: “Fits selected Cummins QSL / QSL9.3 / QSC8.3 / ISL / ISLE 8.9 applications. Please verify by Engine Serial Number, CPL, ECM type, fuel-system type, old injector number, and injector photos before ordering.” Cummins official QSL9 information identifies the QSL9 as an 8.9 L inline 6-cylinder diesel engine using a high-pressure common rail fuel system, with published marine ratings around 290–410 hp depending on rating and configuration. Cummins also states that the QSL9 high-pressure common rail fuel system maintains high injection pressure regardless of engine speed or load condition.
