Cummins 3054049 PTD Fuel Injector Less Link

The Cummins 3054049 is a PTD (Pressure Time Diesel) type fuel injector supplied less link (without the injector connecting rod). It is designed for Cummins PT (Pressure Time) mechanical fuel injection systems where fuel metering is controlled by injection pressure and time. The injector body is manufactured from high-strength alloy steel to withstand cyclic combustion pressures and mechanical actuation loads. The nozzle assembly features precision-drilled orifices for optimized fuel atomization in direct-injection diesel combustion chambers. This component serves as a direct replacement for Cummins part numbers 3054049 and 305404900 across multiple engine platforms including B Series, C Series, L Series, ISB, ISC, ISDe, ISLe, ISZ, QSB, QSL, QSZ, ISM, QSF, ISF, ISG, N Series, K Series, M Series, and QSK series engines. Installation requires the original injector link and calibration to engine-specific PT pump settings.
