Perkins original Perkins 179-9380 HEUI Fuel Injector Replacement for OEM 3408E 3412E D10R D9R Tractor original new injector

The Perkins 3412 Fuel Injector 179-9380 is a direct OEM replacement component engineered for Perkins 3412, 3412B, 3412C, and 3412D series diesel engines. Built as a V12 water-cooled configuration, this injector assembly is designed for generator sets, marine propulsion engines, and heavy-duty industrial power units. It serves a broad range of applications including diesel gensets, marine vessels, mining trucks, oilfield equipment, construction machinery, and emergency backup power systems across power generation, marine, mining, oil & gas, and construction industries worldwide.

This injector assembly features a precision-machined nozzle with OEM calibrated fuel flow, ensuring accurate fuel metering and precise fuel atomization. The internal components are built with corrosion-resistant materials to withstand continuous operation in harsh industrial environments. It is fully compatible with high-pressure fuel systems, delivering improved combustion efficiency, increased engine power output, reduced fuel consumption, lower emissions, reduced engine vibration, and improved cold-start performance, all contributing to extended engine service life.

Prior to installation, fuel lines should be cleaned thoroughly, the injector bore inspected, and any damaged seals replaced. Perkins torque specifications must be followed, with leak inspection and injector operation verification performed after startup. Routine maintenance includes fuel filter replacement, injector spray pattern inspection, fuel pressure testing, and combustion performance analysis to prevent common issues such as hard starting, black smoke, reduced power, excessive fuel consumption, rough idle, and cylinder misfire.
