original 295-9166 Diesel Fuel Injector for C7 Excavator 20R-9079 328-2585 20R-8066 new injector original new injector

The 295-9166 fuel injector is engineered as a direct-fit replacement for the C7 ACERT diesel engine, utilizing the Electronic Unit Injection (EUI) system to deliver precise fuel metering and high-pressure injection performance. Manufactured to OEM calibration standards, this injector assembly ensures excellent fuel atomization, improved combustion efficiency, and reduced fuel consumption across a wide range of operating conditions, making it a reliable solution for heavy-duty industrial applications.

This injector is fully compatible with the C7 engine series, including C7, C7 ACERT, C7 ATAAC, and the C7 Industrial, Truck, Marine, and Generator variants. Cross-referenced with part numbers 10R-7672, 387-9433, 328-2574, 293-4072, 236-0962, and 249-0712, the 295-9166 serves construction equipment, vocational trucks, marine propulsion systems, generator sets, mining machinery, and agricultural equipment. Its corrosion-resistant construction and OEM-grade materials contribute to a long operational lifespan, lower exhaust emissions, faster throttle response, and reliable cold-start performance under demanding workloads.

Installation is straightforward as a direct replacement unit, but proper procedure is essential for optimal performance. Technicians should clean the fuel system thoroughly before installation, replace all injector seals and washers, follow torque specifications, and conduct leak testing and engine performance verification after fitting. Use of OEM-grade fuel filters and clean diesel fuel, along with periodic injector diagnostics and ECM programming verification, will help maintain fuel pressure within specification and ensure the long-term reliability of the C7 fuel injection system.
