This Perkins C7 7.2L HEUI diesel fuel injector is identified by the authorized primary OE number 387-9430 / 3879430 and is engineered as a direct original equipment replacement for the Perkins C7 HEUI diesel engine platform. The unit operates within the HEUI fuel system, where electronically controlled actuation combined with high-pressure oil energy intensification delivers precise injection events required by medium-duty and industrial applications. Each injector is built to OE specification, utilizing coated plungers and durable internal components that withstand the demands of low-sulfur and low-lubricity diesel fuels commonly found in commercial and off-highway environments.

The injector carries an extensive list of authorized cross-reference numbers for verified interchangeability, including 20R-8057, 10R-4761, 10R4761R, 328-2583, 295-1408, 243-4502, 236-0973, 241-3238, 233-3536, 222-5959, 222-5961, EX634761, 634761, 148-012-0001, 254-4339, 712346AT, and CA3879430. This broad cross-reference coverage supports fitment across Ford F650, Ford F750, Chevrolet Kodiak, GMC TopKick, Blue Bird, Thomas bus, Perkins C7 excavator, C7 generator sets, school buses, construction equipment, mining equipment, and industrial power generation units. Both single-piece and six-piece set supply options are available to accommodate single-injector service or full engine overhaul requirements, with export-grade packaging ensuring safe transit for international distribution.

Every injector undergoes flow testing, leak testing, and nozzle atomization quality verification prior to shipment, confirming consistent metering and spray pattern performance. Technical fitment confirmation is provided to support distributor and fleet purchasing decisions. Routine maintenance practices such as using clean diesel fuel, scheduled fuel filter replacement, water separator draining, and inspection of injector electrical connectors help maximize service life and prevent common symptoms including hard starting, rough idle, engine misfire, white or black smoke, high fuel consumption, low power, and diesel knock.
