Perkins original Perkins 250-1311 High Precision Diesel Fuel Injector for 3516B 3512B 3512C 3516C C3500 Excavator Engine original new injector

The Perkins 3512B Fuel Injector 250-1311 is a precision-engineered high pressure diesel injection component designed for demanding industrial and marine applications. Manufactured to OEM specifications, this injector integrates seamlessly with Perkins 3512B, 3512C, 3516, 3516B, 3516C, and 3508 engine platforms, delivering reliable fuel metering and consistent spray patterns under continuous heavy-duty operation.

Each injector body is produced using CNC machining technology with micron-level tolerances, featuring multi-hole nozzle geometry that optimizes fuel atomization and combustion uniformity. Critical moving components receive specialized heat treatment for enhanced wear resistance, while corrosion-resistant materials ensure dependable performance in marine, offshore, and high-humidity environments. The unit is engineered to operate under extreme injection pressures, supporting reduced fuel consumption, fast transient load response, and extended service life across thousands of operating hours.

Designed as a direct replacement for OE part 250-1311 with cross references including 10R0957, 10R0958, 10R0960, 190-4976, and 236-3271, this injector is suitable for power generation sets, data center backup systems, mining equipment, marine propulsion, offshore platforms, oilfield machinery, industrial pumping stations, and emergency standby power installations. Proper installation following Perkins service procedures, including cleaned injector bores, lubricated O-rings, correct torque application, and post-installation leak and pressure verification, ensures optimal injector performance and long-term reliability.
