The Perkins C12 C10 diesel fuel injector 317-5279 is engineered for precision fuel delivery in demanding heavy-duty applications. Designed as an OEM-style replacement, this injector provides stable fuel atomization, consistent injection pressure, and reliable solenoid response across a wide range of Perkins C10 and Perkins C12 diesel engine platforms. Each unit is professionally tested for flow rate, leakage, spray pattern, and injector performance to support remanufacturing programs and global cross-number searches for distributors, fleet operators, and service workshops.

This injector is compatible with an extensive range of cross-reference numbers, including 229-5918, 212-3462, 10R-0961, 10R-0963, 10R-1258, 0R-4987, 0R-9530, 161-1785, 166-0149, 203-3464, 212-3469, 223-5328, 10R-1003, 10R-1814, and FS10R1814. It is suitable for heavy-duty trucks, construction machinery, excavators, loaders, bulldozers, road machines, diesel generator sets, mining equipment, quarry machines, off-road diesel equipment, marine auxiliary engines, and industrial diesel power units, provided the engine serial number and original injector part number are confirmed before installation.

Proper installation requires verifying the injector number, cleaning the injector bore, replacing seals and O-rings, lubricating new seals, and tightening the injector to the official service manual torque specification. After installation, the fuel system should be primed and inspected for leaks, smoke, misfire, rough idle, and diagnostic fault codes. Routine maintenance includes using clean diesel fuel, replacing fuel filters, draining the water separator, and checking injector balance to prevent hard starting, black smoke, power loss, and high fuel consumption.
