The Caterpillar CAT diesel fuel injector 211-0565 — also indexed as 2110565 and 211 0565 — is a heavy-duty fuel injector assembly (Injector GP-Fuel) serving Caterpillar diesel engine aftermarket and replacement supply chains. As the core fuel-delivery component of the engine, this high-pressure injector assembly supports the combustion performance, fuel efficiency, and uptime of CAT-powered equipment operating in demanding industrial environments.
This injector is widely referenced for CAT C15 and C18 diesel engines, with supplier listings also connecting it to C13 and 3406E applications. The Cat C15 industrial diesel engine is officially rated from 354–433 bkW (475–580 bhp), underscoring the heavy-duty class this injector serves. Typical equipment coverage includes excavators, trucks, generators, marine power units, and construction machinery across construction, mining, oil & gas, agriculture, and industrial power markets. For sourcing flexibility, 211-0565 cross-references to 211-3028 and 10R-7228, with additional market numbers 253-0618, 10R-7231, 10R-7213, 291-5911, and 10R-7230.
Designed as a direct replacement after part-number and engine-serial verification, the 211-0565 injector is available in new, replacement, aftermarket, and remanufactured-style options depending on supplier, giving engine rebuilders, diesel workshops, fleet maintenance teams, parts wholesalers, and exporters flexible procurement choices. Because CAT injectors are highly dependent on engine arrangement and serial number, always confirm fitment via the existing injector number, engine model and serial number, machine model, ECM / fuel system configuration, injector body marking, and official Cat parts lookup before ordering.
