Engineered for demanding diesel powertrains, the 222-5966 HEUI Diesel Fuel Injector is a direct replacement solution for 3126, 3126B, 3126E, and selected C7 engines. Cross-referenced with 10R-0781, 197-7107, 198-6605, 199-6065, 222-5926, EX630781, CA2225966, CA10R0781, CA1977107, CA1986605, CA1996065, and CA2225926, this unit supports global B2B buyers seeking multi-number search coverage and reliable interchange for inline 6-cylinder platforms. Available as a single injector or full 6-piece set, it serves diesel repair shops, engine rebuilders, fleet operators, marine service companies, and parts distributors worldwide.
Built on the Hydraulically Actuated Electronically Controlled Unit Injector platform, the 222-5966 delivers precision fuel metering and optimized atomization for more complete combustion, improved engine response, and better fuel efficiency. Heavy-duty construction withstands the vibration, thermal load, and duty cycles typical of truck, marine, construction, and industrial applications. Stable injection response under variable engine loads reduces rough idle, misfire, and unstable running. Reman availability tied to 10R-0781 provides a cost-effective alternative to new units while maintaining consistent performance across all six cylinders.
Proper commissioning is critical: verify engine serial number, arrangement number, old injector part number, trim code, and ECM calibration before installation. Use clean diesel fuel, replace fuel filters, maintain oil quality for HEUI actuation, and prime the fuel system before startup. Professional installation is recommended to ensure long service life and diagnostic compliance.
