Engineered for demanding heavy-duty operation, the 250-1312 diesel fuel injector delivers OEM-standard performance for the 3512B V12 turbocharged and aftercooled diesel engine platform. Designed as a direct replacement, this injector is fully interchangeable with cross numbers 10R-1275, 20R-0849, 162-8813, 204-2067, 229-1631, 245-8272, 246-1854, 250-1311, 250-1302, and 386-1758, providing sourcing flexibility for global industrial buyers, distributors, and MRO fleets.
At the core of its performance, this fuel injector receives high-pressure diesel fuel and precisely meters the appropriate volume according to ECU commands. Fine nozzles atomize the fuel for effective combustion, supporting efficient direct ignition that maximizes power output while reducing fuel consumption and emissions. Corrosion-resistant materials and OEM-grade build quality ensure extended service life under continuous industrial loads, making the unit ideal for generator sets, marine propulsion systems, mining power modules, oil & gas power packs, construction diesel engines, and emergency backup installations.
For reliable performance, follow routine protocols including scheduled fuel filter changes, injector leak tests, fuel pressure checks, injector balance evaluations, and fuel contamination monitoring. Before installation, thoroughly clean fuel lines, replace all seals, apply correct torque specifications, perform ECU injector coding when required, and complete a post-install fuel pressure test. Common symptoms such as hard starts, abnormal smoke, rough idle, and unstable engine power should be diagnosed via pressure and balance testing to confirm injector condition.
