The Perkins 3512B Fuel Injector 10R-3255 is an original equipment diesel fuel injector engineered for the Perkins 3512B engine platform, including 3512B HD, 3512B Marine, 3512B Generator Engine, and 3512B Industrial Power Unit configurations. Manufactured to exact dimensional tolerances, this injector delivers a precise spray pattern and consistent fuel delivery, supporting reliable combustion under the demanding conditions encountered in power generation, marine propulsion, mining operations, and oilfield applications.

Constructed from industrial-grade metallurgy, the 10R-3255 injector is built for high-combustion-temperature environments and continuous-duty operation, offering thousands of operating hours before scheduled overhaul when properly maintained. Its optimized atomization characteristics improve combustion efficiency, reduce fuel consumption, and help control smoke and particulate emissions, making it suitable for data centers, hospitals, offshore platforms, commercial shipping fleets, and heavy industrial facilities across global markets including North America, Europe, the Middle East, Asia Pacific, and Latin America.

Compatible with authorized replacement numbers 386-1769, 392-0217, 230-9457, and 20R-1278, this injector is widely supported through Perkins dealer networks and international diesel parts suppliers. Installation requires inspection of the injector seat, fuel line cleanliness, cylinder head sealing area, fuel contamination level, and engine ECM calibration. Following preventive maintenance practices—including the use of high-quality diesel fuel, regular filter replacement, water separator draining, and exhaust smoke monitoring—ensures long service life and sustained engine performance.
