Engineered for the Caterpillar 3500 Series platform, the CAT 250-1304 fuel injector assembly is an original-specification electronic unit injector developed for the 3512B V12 diesel engine, with proven compatibility across the 3512C, 3516B, 3516C, 3508B, and 3508C engine family. It serves power generation, marine propulsion, mining, oil and gas, heavy construction, and industrial pumping applications where consistent fuel delivery is critical to uptime.
Functioning as a high-pressure fuel metering device, the injector delivers precisely measured diesel quantities into the combustion chamber. The engine ECM calculates fuel demand according to load, RPM, temperature, and operating conditions, then signals the injector solenoid to actuate at exact timing intervals. Fuel passes through precision-machined multi-hole nozzles, achieving superior atomization that mixes efficiently with compressed air—optimizing combustion efficiency, power output, fuel economy, and emissions control.
Every 250-1304 injector is manufactured to micron-level tolerances from high-strength alloy steel with an anti-corrosion precision coating, providing lasting resistance to wear, high-temperature fatigue, and fuel contamination. As a direct OEM-specification replacement, it installs without modification and remains fully compatible with Caterpillar maintenance and overhaul procedures worldwide. Comprehensive cross-referencing—10R-1278, 392-0225, 392-0226, 392-0212, 392-0213, and 392-0214—simplifies global sourcing and interchangeability. New, OEM, and remanufactured conditions are available, backed by ISO 9001 quality standards and a 12-month warranty.
