Engineered as a direct OEM-equivalent replacement for the C7 diesel platform, the 10R-7225 Fuel Injector delivers precision-metered, high-pressure fuel atomization required by modern Electronic Unit Injection (EUI) systems. Manufactured from high strength alloy steel with a corrosion-resistant surface treatment, this injector provides the durability and thermal stability demanded by continuous-duty industrial, on-highway, and marine applications. Each unit is calibrated to OEM flow specifications, ensuring stable idle, optimized combustion efficiency, and reduced emissions across the full C7 engine family, including C7 ACERT, industrial, truck, generator, and marine variants.

The 10R-7225 is a fully interchangeable cross-reference for OE numbers 2490713, 3282574, and 3879433, making it a versatile stocking SKU for global distributors and fleet maintenance operators. Typical installations include excavators, wheel loaders, motor graders, on-highway trucks, generator sets, industrial power units, and marine propulsion systems serving construction, mining, power generation, oil & gas, agricultural, and municipal sectors across North America, Europe, the Middle East, Africa, Southeast Asia, and Latin America.

Recommended service practices include using clean high-quality diesel, replacing fuel filters on schedule, monitoring rail pressure, and checking injector balance rates. Installation requires new sealing washers, O-rings, specified torque, harness reconnection, fuel priming, and post-install calibration. Backed by a 12-month warranty; MOQ 1 piece.
