This CAT-branded 3126 series HEUI diesel fuel injector is a reman replacement component designed for compatible CAT diesel engine platforms. It carries the official OE part number 222-5966, and is specified to fit 3126, 3126B, 3126E and C7 diesel engine models, serving as a standard OE-spec matching repair part for fuel system maintenance and full replacement needs.

The injector supports a full set of listed cross-reference numbers covering multiple part number formatting conventions, including hyphenated and non-hyphenated OEM codes, CA-prefixed CAT part numbers, and EX-series interchange identifiers. All listed cross numbers map to the exact same product specification, reducing part mismatch risks for diesel engine parts distributors, independent maintenance workshops and fleet management teams during sourcing, stocking and inventory management workflows.

It fits heavy-duty applications across truck, marine, construction and industrial engine equipment, making it ideal for bulk purchase for engine overhaul projects, after-sales service parts stock and scheduled heavy equipment maintenance plans. Suited for both small-batch repair orders and large-volume supply contracts, it integrates seamlessly into B2B industrial component supply chains with clear, traceable part identification via official OE and cross reference numbering.
