Cummins original For Cummins QSL9.3 QSL9.5 QSC8.3 Engine, Fuel Injector 4359204, Spare Parts for Excavator, Diesel Fuel Injector Replacement original new injector

Designed for buyers sourcing Cummins diesel fuel-system components, the 4359204 injector is presented as an original-type common rail injector assembly for selected QSL, QSL9.3, QSC8.3, ISL, ISLE 8.9 and QSC applications. The primary OE reference is 4359204, while 435-9204 and C4359204 are useful alternate search formats. Its diesel common rail configuration makes it relevant to engine parts distributors, rebuilders and maintenance teams managing Cummins-powered equipment.

The associated QSL9 engine platform is an 8.9 L inline six-cylinder diesel engine using a high-pressure common rail fuel system. Cummins publishes marine ratings of approximately 290–410 hp, depending on rating and configuration, and states that the system maintains high injection pressure regardless of engine speed or load. For B2B sourcing, this injector can be positioned across marine, construction, generator set, truck, bus, agricultural, industrial power and heavy-equipment supply channels, including engine rebuild and fleet maintenance programs.

To reduce fitment risk, compatibility should not be confirmed by part number alone. Buyers are advised to submit the engine serial number (ESN), CPL, ECM type or calibration, emissions level, fuel-system type, engine model, old injector number and clear injector photographs for verification. Public supplier references are not official Cummins QuickServe fitment records, so these checks are essential before ordering. This verification-led approach supports more accurate quotations, cleaner cross-reference matching and dependable procurement for global diesel spare-parts requirements.
