Reliable fuel delivery is the foundation of every high-output diesel engine, and the Caterpillar 250-1314 fuel injector is engineered to provide exactly that. Built for the CAT 3512B platform, this OEM-specification injector meters fuel with precision and delivers it at high pressure directly into the combustion chamber. As the needle lifts at design pressure, fuel is atomized into micron-scale droplets that mix with compressed air, producing maximum power, cleaner combustion, reduced soot, and lower fuel consumption.
The 250-1314 (2501314) is fully compatible with Caterpillar 3508B, 3512B, and 3516B diesel engines, including PM3512 and PM3516, across industrial power generation, marine propulsion, mining, and oil & gas applications. It serves prime and standby generator sets, marine propulsion and auxiliary systems, heavy-duty mining trucks, and offshore power modules. For sourcing and verification, the injector carries a complete cross-reference network: reman 10R-1290, service exchange 20R-1275, and cross numbers 392-0214, 386-1766, 229-0193, 150-4456, 126-7995, 114-6469, 0R-8892, and 0R-8690.
Manufactured from high-strength alloy steel with corrosion-resistant materials and a thermal-stress design, the injector maintains OEM tolerances and a clean, uniform spray pattern over a long service life. Each unit is individually sealed and produced under ISO and CAT manufacturing standards, with OEM warranty available. At installation, clean the bore, fit new O-rings, inspect the seat and tip, apply correct torque, and perform leak and spray-timing checks. Contact us for bulk pricing and availability.
