Engineered for the punishing demands of heavy-duty combustion environments, the Caterpillar 3512B Fuel Injector 379-0509 (also written 3790509) is a precision high-pressure common rail diesel injector purpose-built for CAT 3512B industrial diesel engines. Compatible with multiple serial variations across the broader CAT 3500 series, it is manufactured from industrial-grade alloy steel and engineered to match CAT OEM performance parameters, ensuring dependable operation wherever 3512B engines are installed.
At the heart of its performance is a precision valve design that injects atomized diesel into each cylinder at exact timing and pressure. Fine fuel atomization promotes complete combustion, cutting unburned fuel and emissions while improving power output and fuel economy. The injector's high-pressure capability is designed for CAT 3512B fuel system pressures, and its durable alloy steel construction resists wear and extreme temperatures, extending service life in severe-duty operation.
Global sourcing is simplified by an extensive interchange database: alongside OEM 379-0509, the injector cross references 0R-3539, 389-1969, 386-1767, 386-1758, 392-0208, 10R-3255, 20R-1272, 392-2000, 359-5469, 250-1312, 250-1314, 386-1774, 392-6214, and more. Widely applied in generator sets, marine propulsion, mining machinery, construction equipment, and oil & gas pump systems, and backed by a typical 6–12 month industrial warranty, 379-0509 offers fleet operators a reliable, supply-chain-friendly replacement solution.
