Caterpillar original Caterpillar C10 C11 C12 C13 Engine Common Rail Fuel Injector 212-3462 147-0373, Replacement for OEM 153-7923, 203-7685 for Diesel Engine Applications original new injector

Consistent combustion performance in heavy-duty diesel engines depends on precise fuel delivery, and the Caterpillar 212-3462 fuel injector is engineered to provide exactly that. Designed for CAT C13 engine platforms, this common rail injector meters and atomizes diesel fuel at high pressure, delivering a stable, finely dispersed spray into the combustion chamber. The result is efficient combustion, dependable power output, optimized fuel economy, and reduced emissions under demanding industrial operating conditions.

Manufactured to OEM-equivalent standards, the 212-3462 injector combines a high-strength alloy steel body with wear-resistant internal components, corrosion-resistant construction, and an industrial-grade sealing system to ensure long service life. Its precision nozzle maintains consistent spray characteristics during high-pressure operation, helping to reduce engine knocking and support long-term engine reliability. Supplied as an original new replacement component, the injector is typically covered by a 12-month warranty, offering buyers dependable quality for critical fuel system repairs.

The injector is compatible with the complete CAT C13 engine family, including C13 ACERT, industrial, marine, generator set, and power unit configurations. Typical equipment applications cover excavators, wheel loaders, mining machinery, heavy-duty trucks, oilfield machinery, generator sets, and marine propulsion systems across global markets. To achieve reliable performance, technicians should clean the injector bore, replace sealing components, follow Caterpillar service procedures, and verify fuel pressure after installation, while clean diesel fuel and regular fuel filter replacement help extend injector service life.
