Cummins 3008706 Injector Filter Screen

The Cummins 3008706 injector filter screen is a critical fuel system component designed to protect high-pressure injectors from particulate contamination. Constructed from 200 mesh stainless steel wire cloth with a copper crush ring, it provides precise filtration for PT and HPI fuel systems. This screen serves as a direct replacement for Cummins part number 3008706 and Interstate-McBee M-174298. It is engineered for compatibility with Cummins KT, QSK, N14, ISX, QSX, QSM11, and K50 series diesel engines used in heavy-duty truck and construction equipment applications. The component functions as a final filtration barrier at the injector inlet, preventing nozzle erosion and maintaining fuel metering accuracy.
