Engineered for demanding diesel operations, the 20R-8059 Fuel Injector is a genuine OEM remanufactured component designed for C7, C7 ACERT, and related industrial, marine, generator, and truck engines. Utilizing Electronic Unit Injection (EUI) technology, this injector delivers precise fuel atomization for improved combustion efficiency, reduced emissions, and stable output under continuous heavy-duty operation. Cross-referenced part numbers include 20R-8059, 328-2576, and 10R-7672.

Built to withstand extreme working environments, this injector assembly ensures high durability, long service intervals, and reduced downtime for fleet operators and industrial end users. Its optimized nozzle design enhances cold starting performance, minimizes injector deposits, and lowers overall fuel consumption. Typical applications include excavators, wheel loaders, motor graders, power generation units, marine propulsion systems, heavy-duty trucks, and agricultural machinery across construction, mining, transportation, and marine sectors worldwide, including North America, Europe, the Middle East, Southeast Asia, Australia, Africa, and South America.

For optimal service life, use clean diesel fuel, replace fuel filters regularly, and follow scheduled preventive maintenance. Installation should follow the service manual using OEM sealing components, with injector calibration verification and ECM diagnostics performed after replacement. Recommended diagnostics include injector balance test, cylinder cutout test, fuel pressure analysis, leak-off test, and nozzle spray pattern evaluation to ensure reliable performance and lower total cost of ownership.
