c-aterpillar 3412 Series Fuel Injector (Model 20R-0758) Product Details

Product Core Overview

The c-aterpillar 20R-0758 fuel injector is an OEM-standard fuel injection component exclusively engineered for the 3412 series diesel engines, with full compatibility for 3408 series engines. Classified as a high-pressure common rail diesel injector, this part is manufactured in strict accordance with c-aterpillar’s original production processes and precision standards. Its core components are constructed from high-strength wear-resistant materials, delivering superior fuel atomization, stable fuel supply pressure, and long-lasting durability. It is perfectly suited for heavy-duty applic-ations including construction machinery, generator sets, and marine power systems.

This injector serves as a direct replacement for OEM part numbers 174-7526, 174-7528 and other equivalent models. It effectively resolves common engine malfunctions such as power loss, excessive fuel consumption, rough idle, and abnormal exhaust smoke, fully restoring the engine’s original power output and fuel efficiency. It is the optimal choice for maintenance, repair and component replacement of heavy-duty equipment.
