For B2B parts distributors, fleet operators and engine rebuilders sourcing reliable Caterpillar fuel system components, the CAT 0R-3389 (alternatively written as 0R3389) fuel injector is an original-standard solution for heavy-duty diesel engine applications. Classified as an Injector GP on Caterpillar’s official parts platform, it is available in multiple stock configurations including genuine Cat Reman, remanufactured, new aftermarket and rebuilt units to suit diverse budget and operational requirements. The injector is engineered to match the performance specifications of CAT 3116 series engine fuel systems.
The 0R-3389 is cross-referenced with a range of Caterpillar interchange numbers, including high-priority codes 4P-2995, 0R-8471 and 7E-8952, to support catalog matching, RFQ processing and aftermarket part searches. Designed primarily for CAT 3116 inline 6-cylinder diesel engines, it may appear in listings for 3114 and 3126 related engine platforms, as well as truck, marine, generator and construction machinery installations. All non-primary fitments require verification via engine serial, arrangement and original injector numbers prior to purchase.
This mechanical unit injector is suitable for professional use cases including diesel engine repair, reman engine rebuilding, fleet maintenance, industrial equipment service and marine diesel servicing. It is sold individually, with six units required for a complete overhaul of a 6-cylinder 3116 engine, and must be installed by professional diesel technicians to ensure proper operation. Its original-specification design supports consistent fuel delivery and reliable performance in demanding heavy-duty operating environments.
