Engineered for the Caterpillar 3512B, a V12 turbocharged and aftercooled diesel engine, the CAT 250-1312 fuel injector is an OEM-quality replacement solution for heavy-duty industrial power systems. This injector cross-references with part numbers 10R-1275, 20R-0849, 162-8813, 204-2067, 229-1631, 245-8272, and 246-1854, giving parts distributors and service technicians flexible sourcing options across global service databases. It is also compatible with related 3512 industrial, marine, and power generation engine models.
Built to operate within the 3512B's high-precision electronic unit injection system, the injector receives high-pressure diesel fuel, meters the exact volume according to ECU commands, and atomizes it through fine nozzles for efficient direct combustion. Precision fuel metering and high-pressure atomization optimize combustion efficiency, maximizing engine power while reducing fuel consumption and emissions. Corrosion-resistant materials and OEM-standard build quality ensure extended service life under demanding industrial conditions.
The 250-1312 injector is widely applied in industrial generator sets, Caterpillar marine propulsion engines, mining power modules, oil & gas power packs, construction diesel engines, and emergency backup systems. For reliable performance, clean fuel lines thoroughly before installation, replace all seals, apply Caterpillar torque specifications, and perform ECU injector coding where required. Scheduled fuel filter changes, leak tests, and injector balance evaluations are recommended to sustain long-term durability. Contact our team for bulk pricing, availability, and technical support.
