Caterpillar original Diesel Fuel Injector 392-9046 for C9 C9.3, Replacement for OEM 20R-5077, Fuel Injector 382-0709, Cross Reference 367-4293 for Sprayer Excavator Truck 336ELN original new injector

Tailored for industrial B2B procurement, engine rebuild and equipment maintenance use cases, the CAT 392-9046 is a purpose-built common rail diesel fuel injector for Caterpillar C9.3 engine platforms. It delivers precisely metered diesel fuel to the combustion chamber at calibrated timing, with optimized spray pattern and injection quantity to support consistent engine operation. Built with Caterpillar’s specialized metallurgy and proprietary manufacturing processes, it is engineered to meet required performance, injection pressure and emissions standards for C9.3 series engines.

A range of supplier-listed cross reference numbers are associated with this injector, but broader database references including 20R-series part numbers are classified as related family or supply-chain references only, not automatic direct replacements. To avoid procurement errors, all compatibility checks must be completed prior to order confirmation, including verification of engine serial number, arrangement number, original injector part number, equipment model and ECU configuration requirements.

This injector supports a wide range of C9.3 engine variants spanning ACERT, C9.3B, marine and generator-set configurations, for use across excavators, construction machinery, mining support equipment, marine propulsion systems and stationary diesel generator sets. It is suitable for repair shops, engine rebuilders, fleet operators, parts distributors and global industrial procurement teams, with multiple supply condition options available to match different operational requirements.
