Cummins original Replacement for OEM Fuel Injector Assy 3083849 Fit for M11 ISM ISM11 ISM350 QSM QSM11 ISM Series Diesel Engines Cross Ref Nos 3411754 3411756 original new injector

The Cummins M11 fuel injector 3083849 is an OEM replacement designed for the M11, M11 Plus, ISM11, and QSM11 diesel engine platforms. This injector is directly compatible with CELECT and CELECT Plus fuel systems, ensuring precise fuel delivery across heavy-duty truck, bus, construction, mining, and marine applications. It replaces multiple OE numbers including 3411756, 3411756PX, 3411756R, 3411756RX, EX631756, and others, making it a versatile solution for fleet maintenance.

Precision CNC machining and OEM tolerance standards guarantee optimal fuel metering, atomization, and injection timing control. The heat-treated alloy steel construction and corrosion-resistant materials provide high durability under extreme pressure conditions, resulting in improved combustion efficiency, stable idle operation, reduced fuel consumption, and lower exhaust emissions. These performance benefits directly contribute to extended engine life and reduced operating costs.

For reliable long-term service, use OEM-quality fuel filters, clean diesel fuel, and regularly drain water separators. During installation, disconnect the battery, clean the injector bore, replace sealing washers, lubricate O-rings, and torque to Cummins specifications. Bleed the fuel system, verify injector coding if required, then start the engine and inspect for leaks. Proper maintenance and installation minimize downtime, making this injector a cost-effective choice for heavy-duty operations.
