Engineered for the 3412 engine platform, the 222-5967 fuel injector assembly is a diesel fuel-system component designed for precise metering and consistent delivery under high-pressure operating conditions. Its controlled opening and closing sequence supports fine fuel atomization, efficient air-fuel mixing and complete combustion, helping maintain reliable power output while reducing fuel consumption, exhaust emissions and combustion-related wear.

Built to OEM specifications, the injector combines heavy-duty industrial construction, high-strength alloy materials and a corrosion-resistant finish for demanding operating environments. Hardened, wear-resistant internal components support extended service life, while high-temperature resistance suits continuous heavy-load operation. The direct-injection design provides accurate fuel delivery for each combustion cycle and an enhanced spray pattern, with OEM replacement fitment for installation in the cylinder-head fuel injection system.

The 222-5967 injector is compatible with 3412, 3412B and 3412C engines, including 3412 DITA, marine, generator, industrial power-unit and mining configurations. Typical uses include generator sets, marine propulsion, mining trucks, industrial power plants, oil and gas equipment, offshore platforms, construction machinery and emergency backup power systems. Cross references include 0R-8682, 10R-0955, 170-5187 and 212-3467. Before ordering, verify the engine serial number and original injector number. During service, clean the injector bore, replace sealing washers, follow torque and service procedures, then bleed the system and check for leaks. Regular fuel-filter replacement and clean diesel fuel are recommended.
