Engineered for demanding diesel platforms, the Cummins 3411754 fuel injector delivers reliable fuel atomization and consistent metering across the M11 and N14 engine families. Built to OEM calibration standards, this injector assembly restores factory-level combustion efficiency in CELECT and CELECT Plus fuel systems, making it a dependable replacement solution for fleets and industrial operators seeking sustained performance and reduced downtime.

This injector integrates precision machining, high pressure fuel delivery, and heat resistant components to withstand the thermal and mechanical stresses of continuous operation. Corrosion protection and a low leakage design support long service intervals, while heavy duty construction ensures durability under prime power and high-load conditions. Direct OEM fitment allows straightforward installation on Freightliner, Kenworth, Peterbilt, International, Volvo, and Mack trucks, as well as excavators, loaders, mining equipment, marine auxiliary engines, and generator sets. Verified cross references include 3411754RX, 3803474, 3802924, 3087648, 3076704, 3411760, 3411761, and 3411762.

Proper maintenance maximizes injector life: inspect the fuel filter at 250 hours, the fuel system at 500 hours, test injector performance at 1,000 hours, clean injectors at 2,000 hours, and perform a comprehensive inspection at 5,000 hours. This component effectively addresses hard starting, excessive smoke, power loss, rough idle, high fuel consumption, engine knock, misfire, and elevated exhaust emissions.
