Engineered for demanding industrial diesel applications, the 387-9429 HEUI fuel injector delivers precise fuel metering and reliable atomization for C7 and C7 ACERT 7.2L diesel engines. This injector is a direct OEM-specification replacement designed to restore original engine performance across a wide range of heavy-duty platforms, and it cross-references directly to 10R-4762, 20R-8058, 222-5962, 236-6011, 238-9808, 241-3239, 243-4503, 295-1409, 328-2584, EX634762, FS10R4762 and R10R4762 for streamlined global sourcing.
Built using high-strength steel internals, a precision plunger assembly and a multi-hole nozzle, the injector operates through hydraulic amplification of engine oil pressure combined with electronic solenoid control from the ECM. Specialized anti-corrosion coatings protect against fuel contamination and moisture ingress, ensuring dependable long-service performance in severe-duty environments. Each unit is manufactured to strict dimensional standards, delivered brand new, and 100% bench tested to verify spray pattern, response time and leak integrity, supporting improved fuel economy, reduced particulate emissions, better cold starting and higher torque output.
Typical applications include excavators, wheel loaders, motor graders, medium-duty trucks such as Freightliner, International, Peterbilt and Kenworth, Blue Bird and Thomas Built buses, prime and standby generator sets, marine propulsion engines, workboats, mining equipment and stationary power units. Recommended service intervals include filter inspection every 250 hours, fuel pressure checks every 500 hours, injector balance testing at 1000 hours, and professional injector evaluation every 3000 hours.
