Cummins original FOOBJ60783 Diesel Fuel Injector Machinery Parts for QSK19 QSK38 QSK50 QSK60 Engine, replacement for OEM 1000019903, cross reference 0986435912 original new injector

The FOOBJ60783 / F00BJ60783 diesel fuel injector is a heavy-duty replacement reference for Cummins QSK19 engines, serving mining, power generation, marine, oil and gas, rail, construction, quarrying, crushing and industrial power buyers. The QSK19 is a 19-liter inline six-cylinder platform; G-Drive versions use a high-pressure fuel pump, Modular Common Rail Fuel System and integrated electronic control. Related listings also mention QSK38, QSK50 and QSK60, but these applications require verification before ordering.

The injector receives high-pressure diesel fuel, opens according to ECM command, and atomizes fuel through precision nozzle holes to support stable combustion, while excess fuel returns through the return circuit. Key sourcing features include precision fuel metering, fine atomization, high-pressure fuel-system compatibility, stable injection response and industrial durability. Export-ready packaging, pre-shipment quality inspection and broad cross-reference coverage support international procurement and efficient replacement-part matching.

Before purchase, confirm the old injector label, engine serial number, CPL number, engine model and fuel-system version. References such as 1000019903, 4955524, 4964170, 4964171 and 0986435616 aid search matching but do not replace interchange verification. During installation, keep the injector bore and fuel-line area clean, replace required seals, and inspect the high-pressure pipe, return line, connector and wiring harness. Use engine-serial-number-specific Cummins service data for procedures and torque values; then prime the fuel system, check for leakage and read diagnostic codes.
