original 379-0509 Common Rail Fuel Injector for C3500B 3152 Diesel Engine Construction Machinery Truck Parts Aftermarket Replacement 20R-1265 386-1753 original new injector

Engineered specifically for demanding industrial diesel applications, this common rail fuel injector (OE 379-0509) delivers reliable high-pressure fuel delivery for the . 3512B engine platform. Constructed from industrial-grade alloy steel, the injector is designed to withstand the elevated combustion pressures, thermal cycles, and continuous-duty cycles typical of heavy-duty power generation, marine propulsion, mining, and oilfield service environments. Its precision valve architecture ensures accurate fuel atomization, promoting complete combustion, improved fuel efficiency, and reduced particulate emissions across the operating range.

Broad interchangeability is a core advantage of this unit. Verified cross reference numbers include 3790509, 0R-3539, 389-1969, 386-1767, 386-1758, 392-0208, 10R-3255, 20R-1272, 392-2000, 359-5469, 250-1312, 250-1314, 250-1308, 250-1304, 20R-0848, 20R-0850, 20R-3483, 386-1760, 386-1771, 386-1774, and 392-6214. This wide compatibility simplifies sourcing for fleet operators, MRO suppliers, and OEM distributors supporting . 3512B installations in stationary generator plants, marine propulsion systems, mining excavators and haulers, construction equipment fleets, and oil field production machines worldwide.

For optimal service life, depressurize the fuel system before removal, clean the injector bore, install with recommended anti-seize, torque to . specifications, and bleed all air prior to startup. Routine inspection every 500 operating hours, timely fuel filter replacement, and approved injector cleaner use will maintain peak performance.
