Caterpillar original Diesel Engine Fuel Injector, Replacement for OEM, fits Caterpillar C10 C11 C13 Engines, compatible with 345C 345D Equipment, primary part number 212-3465 original new injector

Specifically engineered for selected Caterpillar C13 engine platforms, the CAT 212-3465 diesel fuel injector is a precision-manufactured core component of the engine’s high-pressure fuel delivery system. Operating under electronic control from the engine’s Electronic Control Module (ECM), it meters and atomizes high-pressure fuel before delivering it directly into the combustion chamber, supporting optimal combustion efficiency, stable power output, improved fuel economy and compliant emissions performance across C13 ACERT, industrial, generator, marine and truck engine variants.

Manufactured to OEM-equivalent quality standards, this brand-new injector features heavy-duty industrial-grade construction that withstands extreme operating pressures, continuous-duty workloads and harsh environmental conditions. Its precision machining delivers superior fuel atomization, corrosion resistance and long service life, while reducing exhaust emissions, improving cold-start performance and lowering overall operational costs for commercial fleet and heavy equipment operators.

This injector fits a broad portfolio of Caterpillar-powered equipment across construction, mining, transportation, power generation, industrial and marine sectors, including heavy-duty trucks, excavators, wheel loaders, motor graders, generator sets, industrial compressors, pumping systems and marine engines. Always confirm compatibility using the engine serial number (ESN) before ordering, and follow official Caterpillar service protocols during installation to ensure reliable, long-lasting performance.
