Cummins original 5491659 Fuel Diesel Injector Pump 4327072 for Excavator, Fits QSL9.3 QSC8.3 QSL9.5 ISZ13 Engine Spare Parts, Replacement for OEM 4384165, Cross Reference 4359204 original new injector

For part-number-led diesel engine sourcing, the Cummins 5491659 is offered as an original-type diesel common rail injector assembly for selected QSL-related applications. Public supplier references associate it with Cummins QSL, QSL9, QSL9.3, QSC8.3, ISL, ISLE 8.9, ISC, QSC and ISCE-related engines. It supports fuel injection within the applicable common rail system and is relevant to engine repair, rebuild and maintenance purchasing. Professional buyers should match it by part number, engine model and fuel-system configuration, not equipment name alone.

Related market numbers include 4359204, 4327072, 4307414 and 4307452. These references support quotation and inquiry matching, but they are not guaranteed direct replacements without technical confirmation. For application context, Cummins identifies the QSL9 as an 8.9 L inline six-cylinder diesel engine with a high-pressure common rail fuel system; published marine ratings are approximately 290–410 hp, depending on rating and configuration. This engine information does not by itself confirm injector fitment.

The 5491659 injector can be offered to excavator service, construction machinery, truck, bus, marine, generator set, agriculture, industrial power, heavy-equipment, fleet maintenance and export spare-parts channels. Before ordering, buyers should provide the engine serial number (ESN), CPL, ECM type or calibration, emissions level, fuel-system type, engine model, old injector number and clear injector photos. Final compatibility should be checked against the engine build and supplier catalog, helping reduce incorrect selection and supporting accurate B2B quotation.
