original 20R-8067 Diesel Parts Common Rail Fuel Injector Assembly 254-4330 20R-9079 for C7 324D 325D new injector original new injector

The ® Reman fuel injector 20R-8067 is engineered as a direct-fit replacement for the C7 diesel engine family, covering C7 marine engines, C7 industrial engines, C7 generator engines, and C7 construction machinery engines. Also referenced as the C7 2.2 SF application, this injector carries OE-number traceability under part number H1315B and integrates seamlessly with the C7 fuel system. Authorized cross references include 20R8067, 387-9441, 295-9166, 328-2587, 10R-7226, 280-4173, 280-4174, 557-7627, and 20R-9079, ensuring reliable interchangeability for distributors, fleet operators, and heavy-duty maintenance programs.

Manufactured through proprietary reman processes, the 20R-8067 injector incorporates specialized metallurgy, engineering updates, and extensive testing to deliver like-new performance and durability. It is calibrated to operate effectively on modern low-sulfur, low-lubricity diesel fuels, supporting consistent fuel delivery precision under demanding industrial, marine, and power generation workloads. Installation should follow standard service practices, including replacement of injector seals, inspection of fuel lines, and verification of return flow before returning the engine to service.

Operators should confirm the original injector number and engine serial number prior to shipment, particularly when sourcing C7 injectors for related equipment lines. Machine applications such as 324D, 325D, 326D, and 329D may be associated with similar C7 injector numbers, but final fitment must be validated against engine records. Routine maintenance—clean diesel supply, scheduled fuel filter replacement, water separator draining, and periodic cylinder balance testing—helps extend injector service life in the C7 engine platform.
