The Perkins 3512B fuel injector 392-0217 is purpose-built for the Perkins 3508B, 3512B, and 3516B series diesel engines, delivering reliable fuel delivery in continuous and standby power generation, marine auxiliary systems, mining operations, oil and gas pumping, and large-scale backup power modules. Recognized through cross references 20R-1278, 10R-3255, 386-1769, 230-9457, 11R-0286, 10R-7220, and 10R-7220B, this injector offers drop-in compatibility for global service networks and authorized reman programs.

Precision engineered nozzle technology ensures consistent atomization, reduced carbon buildup, and a stable spray pattern. The high-pressure resistance rated up to 160 MPa supports injection accuracy of ±0.5% and a flow rate of 300-400 cc/min. Wear and corrosion resistant alloy steel components with specialized coatings promote long service life, while OEM and reman equivalence meeting or exceeding OEM tolerances delivers dependable combustion efficiency and lower unburned hydrocarbons and soot.

Routine inspection every 500 operating hours is recommended, with checks for fuel leakage at the injector body, nozzle, and fuel lines, plus scheduled spray pattern and flow testing on authorized test benches. Use only high-grade diesel conforming to relevant ISO standards, replace primary and secondary fuel filters regularly, and install new injector seals and copper washers from OEM or approved sources. Torque the injector hold-down per the Perkins service manual, typically 35-45 Nm, and flush the fuel system before installation to eliminate contaminants.
