Engineered as a heavy-duty replacement solution for the C7 7.2L HEUI diesel engine platform, this fuel injector (OE 387-9430) delivers precision fuel metering and reliable atomization for medium-duty trucks, school buses, construction machinery and industrial power units. It cross-references 20R-8057, 10R-4761, 328-2583, 295-1408, 243-4502, 236-0973, 233-3536, 241-3238, 222-5959, 222-5961 and EX634761, providing a broad fitment window for aftermarket distributors and rebuilders.

Utilizing HEUI technology, the injector employs high-pressure engine oil energy and electronically controlled actuation to intensify fuel pressure, while the ECM governs injection timing and duration. Each unit is manufactured with coated plungers and precision nozzle components, then subjected to flow testing, leak testing and atomization quality inspection. The result is fine fuel dispersion, improved combustion efficiency, stable torque output, reduced misfire risk and consistent engine performance across the C7 operating range. Export-grade packaging is available in 1-piece or 6-piece set configurations to suit overhaul workflows.

Recommended for diesel repair shops, fleet maintenance operations, heavy equipment parts distributors, engine rebuilders and international aftermarket resellers serving Ford F650/F750, Chevrolet Kodiak, GMC TopKick, Blue Bird and Thomas bus fleets, as well as C7 industrial and generator applications. Fitment must be verified by original injector number, engine serial number, engine arrangement number, VIN, equipment model, fuel system configuration, ECM calibration and trim code prior to installation.
