Perkins original Perkins 3920214 Diesel Fuel Injector for 3508B 3512B 3516B Engine  original new injector

The Perkins 3512B Fuel Injector 392-0214 / 3920214 is an electronic unit injector engineered for the Perkins 3500 series diesel platform, including Perkins 3512B, 3508B, 3516B, and corresponding 3512C, 3508C, and 3516C variants. Built to OEM specifications from hardened steel alloys, the injector supports extremely high injection pressures while maintaining consistent atomization through a precision-machined multi-hole nozzle. The assembly is calibrated with engine-specific trim codes, ensuring the engine control unit recognizes each unit for accurate injection timing, optimal combustion efficiency, and stable performance across prime power, standby, and heavy-duty industrial duty cycles. Authorized cross references include 386-1766, 250-1314, 229-0193, 150-4456, 114-6469, 126-7995, 132-0204, along with reman equivalents 20R-1275, 11R-0285, 10R-1290, 0R-8892, and 0R-8690, simplifying SKU management for service operations.

The injector is validated for use in marine engines, generator sets, mining trucks, drilling rigs, fracturing pumps, heavy excavators, crawler cranes, and locomotive auxiliary power units. Its corrosion-resistant design, wide operating temperature tolerance, and high-strength alloy construction make it suitable for marine, offshore, and severe-service environments. Routine maintenance is straightforward: depressurize the fuel system, inspect high-pressure lines and seals, install new O-rings, apply OEM-approved anti-seize on threads, and torque the hold-down clamp to Perkins factory specifications of approximately 70–90 Nm. After installation, prime the system, check for leaks, and confirm ECU recognition of the injector trim code for optimal engine response.

Available in both OEM and remanufactured options, the 392-0214 Perkins injector is backed by typical warranty terms ranging from 12 to 24 months. The reman 20R-1275, 0R-8892, and 0R-8690 references deliver a cost-effective alternative for fleet operators and service shops while meeting the same fit, form, and function as the original part. Compatible with diesel generator sets supporting 24/7 prime and standby power, commercial vessels, tugboats, offshore platforms, mining equipment, and rail infrastructure, this injector is a dependable solution for global industrial power applications.
