Purpose-built for Caterpillar C7 7.2L HEUI diesel platforms, the CAT 387-9430 fuel pump injector is an industrial-grade OE replacement component engineered for professional diesel service operations. Developed specifically for Caterpillar diesel engines and validated for use with low-sulfur, low-lubricity fuels, it is intended for C7 engine fuel system repair, engine rebuilding, fleet maintenance, and heavy-duty equipment service workflows.

The 387-9430 injector is indexed under a wide range of OE, remanufactured, supplier, and interchange part numbers to support global B2B parts sourcing. Common cross references include 20R-8057, 10R-4761, 328-2583, EX634761, and other numbers stamped on units or listed in parts catalogs. Buyers must verify fitment via the original injector number, engine serial number, arrangement number, application configuration, ECM calibration, and trim code, as C7 engine builds vary by production year, horsepower rating, and emission configuration.

Available for order as a single unit, 6-piece full engine set, reman exchange unit, or bulk wholesale shipment, the injector serves diesel repair shops, fleet maintenance companies, heavy equipment parts distributors, engine rebuilders, truck parts importers, and industrial diesel service providers. It fits medium-duty trucks (including Ford F650/F750, GMC TopKick, Chevrolet Kodiak), buses (including Blue Bird), construction equipment, and industrial diesel equipment across C7 engine applications.
