Cummins original F00B J00 003 Common Rail Fuel Injector, for heavy duty diesel engine application, Diesel Engine Part, Replacement OEM 2867148, Cross Reference 2882078 original new injector

For heavy-duty diesel maintenance, the Cummins original F 00B J00 003 common rail fuel injector, also written F00BJ00003, is supplied in original new condition for injector replacement, fuel system repair and engine overhaul. Its function is to meter and atomize diesel fuel into the combustion chamber. Correct injector performance helps support stable combustion, strong torque output, smooth idle, normal fuel consumption and reduced visible smoke under demanding operating conditions.

This product is positioned primarily for Cummins QSK19 heavy-duty diesel engine applications. Public supplier listings also associate F00BJ00003 with QSK50 and QSK60 applications; these references require confirmation rather than automatic fitment. Application coverage includes marine propulsion, mining equipment, generator sets, rail power units, oilfield equipment and industrial diesel power systems. The QSK19 platform uses electronic controls and high-pressure injection to support clean, powerful and efficient operation, making accurate injector selection an important part of maintenance.

Related reference numbers include 2867148, 2882078, F00BJ00002, 0986435613, 0986435902 and Y431K05393. Because public listings may mix adjacent QSK injector families and QSK19 engines can differ in ECM version, fuel system, emissions configuration and injector code, compatibility must be verified before ordering. Buyers should provide the engine serial number, CPL, old injector number and injector photo, and confirm the Bosch number, Cummins number, connector type, injector code and fuel system version. Adjacent references should not be treated as guaranteed direct replacements without technical confirmation.
