Cummins original Diesel Engine Fuel Injector 4384360 Fits N14 ISM11 QSM11 M11 QSN14 s for Construction Machinery 3083846T 4307776 3407776 original new injector

Engineered for the demanding operating conditions of Cummins N14 series engines, the 4384360 electronic unit injector delivers dependable fuel delivery for heavy duty diesel applications. Built to OEM calibration standards and identified by primary OE number 4384360, this injector serves as a direct replacement for N14, N14 Celect, and N14 Celect Plus power units operating across long-haul, vocational, industrial, and marine environments.

The injector features a precision machined nozzle, high temperature resistance, and corrosion protection to withstand continuous heavy load cycles. Its reliable electronic performance supports improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, stable idle operation, and enhanced engine response. Cross referenced to part numbers 3411767, 3411768, 3803528, 3803938, and 3802098, it is compatible with Kenworth W900, Peterbilt 379, Freightliner Classic XL, International 9400, and Western Star 4900 platforms, as well as industrial power units and construction machinery.

Proper maintenance maximizes service life: use high-quality diesel fuel, replace fuel filters regularly, avoid contaminated fuel, and perform periodic injector balance tests. Installation requires clean injector bores, new sealing rings, and torque values per OEM specifications, followed by fuel pressure verification and ECM diagnostics. Recommended diagnostic procedures include fuel pressure test, injector resistance test, cylinder contribution test, return flow inspection, and injector leak test for consistent fleet reliability.
