Caterpillar original 392-0208 Fuel Injector Replacement for OEM 20R-0848, compatible with CAT C3500 C3500B Engines for 5130B 5230B Equipment, matching 392-0214 and 10R-1278 original new injector

For industrial operators sourcing reliable fuel system replacement parts for CAT 3512B engine fleets, the Caterpillar 392-0208 high-pressure diesel fuel injector delivers OEM-equivalent fit and consistent performance for mission-critical operations. Designed exclusively for the 51.8L V12 CAT 3512B engine platform, it is compatible with all 3512B variants covering industrial, HD mining, power generation, marine, offshore and oil & gas configurations, and corresponds to cross-reference numbers 3920208, 330-6201 and 3306201 to streamline procurement part matching.

Manufactured to industrial-grade standards with premium alloy steel materials, advanced heat treatment processes and precision-machined internal components, the injector withstands harsh operating conditions including continuous-duty operation, high combustion temperatures, high-pressure fuel system stress, extreme vibration, heavy load fluctuations and extended operating hours. It enables precise fuel metering and optimized spray atomization to support complete combustion, reduce fuel consumption and exhaust emissions, and extend the overall service life of 3512B diesel engines.

Suitable for equipment including generator sets, marine propulsion vessels, mining trucks and machinery, oilfield and gas installations, industrial pumping stations and emergency standby power systems, this brand-new injector delivers stable, consistent fuel delivery across all heavy-duty use cases. It helps reduce unplanned downtime and lower long-term total operational costs for fleet managers and industrial maintenance teams.
