Engineered for the C12 diesel engine family, the 203-3464 fuel injector (also referenced as 2033464) is a heavy-duty electronic unit injector designed to deliver precision fuel metering and fine atomization inside the combustion chamber. Built around the electronically controlled unit injection fuel system of the 12.0-liter inline six-cylinder C12 engine, this injector supports commercial ratings from 340–490 bhp at 1800–2300 rpm across truck, industrial, marine, and off-highway platforms. Cross reference numbers include 10R-1003, 212-3463, 317-5278, 281-7152, 20R-0055, 212-3465, 212-3468, 317-5279, 166-0149, 10R-1258, and 187-6549.
This replacement-ready injector assembly is suitable for heavy-duty trucks, buses, excavators, mining equipment, agricultural machinery, marine propulsion units, generator sets, and industrial power equipment fitted with compatible C12 engines. Key operational benefits include stable idle performance, power recovery support, improved fuel economy, and reduced exhaust smoke. Because C12 engines may use different injector calibrations depending on engine serial number, rating, and emissions configuration, buyers should always verify compatibility against the engine serial number prior to purchase.
Ideal for B2B diesel parts distribution, fleet maintenance programs, engine rebuilding, and heavy equipment service, the 203-3464 injector helps resolve symptoms such as hard starting, rough idle, black or white smoke, misfire, low power, and elevated fuel consumption. Matched-set replacement is recommended during major overhaul to ensure balanced cylinder performance and long-term reliability.
