Carrying the official OE part number OR-9350, each unit comes with a full set of cross-reference part numbers covering 18 interchangeable variants, including both hyphenated and compact number formats as well as legacy alternative part numbers, to streamline part identification for B2B buyers, parts distributors and maintenance teams.
This injector is compatible with 3116 and the full 3126 series HEUI diesel engine lineup, including 3126B, 3126E and 7.2L inline-six diesel configurations. It supports a wide range of on-road, off-road and marine equipment use cases, spanning medium-duty trucks, buses, recreational vehicles, motorhomes, fire trucks, construction machinery, marine vessels and stationary industrial engine setups, making it a high-coverage SKU for multi-scenario parts supply.
As an industrial-grade replacement unit engineered for HEUI fuel systems, this injector matches the form, fit and functional specifications of factory-installed units for targeted engine platforms. It is a practical stocking choice for diesel repair facilities, commercial fleet operators, marine service teams and industrial equipment maintenance departments, with broad cross-number coverage reducing part matching errors across regional sourcing channels.
