original Fuel Injector GP Cross Reference 188-1320, 222-5965, 173-9267, 173-9379 for 3126B, 3126E, 3126 Engine, Replacement for OEM Diesel Nozzle Assembly for Excavator and Truck original new injector

Engineered for erpillar C9.3 diesel engine fuel injection systems, the 173-9379 injector—also aloged as 1739379—is identified in the official Parts listing as “INJ GP-F-C." Although that listing now marks this number as discontinued and advises contacting a dealer for replacement options, it remains widely cross-referenced in aftermarket C9.3 injector alogs. Because erpillar compatibility can vary by engine serial number, arrangement number, injector trim, ECM calibration, and emission configuration, buyers should confirm fitment by serial number, old injector number, or parts book before ordering.

This diesel fuel injector assembly is positioned around OE-style dimensional design, precision fuel metering, industrial-grade construction, high-pressure sealing performance, and improved fuel atomization for heavy-duty operation. For sourcing and aloging, 173-9379 is commonly indexed together with replacement and cross-reference numbers including 367-4293, 456-3493, 456-3509, 456-3589, 138-8756, 155-1819, 169-7408, 232-1173, 232-1183, and 10R-1265. Related alog numbers such as 173-9272, 0R-9348, and CA1739379 also appear in buyer searches; these serve as reference data rather than guaranteed interchangeability for every engine serial number.

Appliion coverage spans erpillar excavators, wheel loaders, track-type tractors, generator sets, marine auxiliary engines, mining equipment, construction machinery, and industrial power units. Some aftermarket alogs additionally associate this injector with 3126, 3126B, 3126E, and E325C excavator appliions, subject to serial-number confirmation. The injector is offered in genuine, OEM, remanufactured, aftermarket, and new tested condition options. Verifying machine model, engine arrangement number, and injector body number before installation ensures correct matching within the engine fuel injection system.
