Caterpillar original Fuel Injector: 392-0214, for heavy duty diesel engine application, 392-0204, 392-0208, 376-0509 – OEM Replacement for Caterpillar Engines & Excavators original new injector

For operators managing heavy-duty CAT 3500 series diesel engine fleets, the genuine Caterpillar 392-0214 (OEM variant: 3920214) electronic unit fuel injector delivers factory-spec performance for mission-critical power, marine and industrial assets. This original-new injector fits compatible CAT 3512B, 3512, 3512C, 3508B, 3508C, 3516B, 3516C and 3500 series industrial engines, with cross-reference coverage for common reman and replacement part numbers to streamline global sourcing. It is a direct OEM replacement for Caterpillar fuel injection systems, eliminating fitment guesswork for maintenance teams.
Engineered to strict Caterpillar fuel system standards, the 392-0214 operates as an ECM-controlled precision metering device, delivering accurately timed, high-pressure diesel to engine combustion chambers. Its multi-hole nozzle and precision-ground needle valve produce finely atomized fuel spray, optimizing air-fuel mixing to boost combustion efficiency, enhance power output, reduce fuel consumption and lower exhaust emissions. Its heavy-duty hardened steel construction and corrosion-resistant design support reliable long-term operation in harsh marine, mining and offshore environments.
Suited for diverse use cases including generator sets, marine propulsion systems, mining equipment, oilfield infrastructure, locomotive power systems, industrial compressors and large construction machinery, the injector includes a 12-month warranty for B2B buyer assurance. Backed by Caterpillar’s global supply chain, it is widely recognized by OEM, aftermarket and remanufacturing partners worldwide. Installation follows official CAT service guidelines covering part verification, bore cleaning, seal replacement, system priming and post-install testing to reduce unplanned fleet downtime.
