The 373-4087 fuel injector assembly is specifically engineered for the 3500 series diesel engines, including the 3508, 3508B, 3512, 3512B, 3516, 3516B, and 3520 models. This injector serves as a direct OEM replacement component, with cross-reference compatibility for part numbers 3734087 and 392-0214, ensuring a precise fit for engines used in mining trucks, generator sets, and marine propulsion systems. The design follows original specifications, making it suitable for demanding heavy-duty industrial environments where engine reliability and consistent fuel delivery are critical to operational performance.

Manufactured with industrial-grade metallurgy and precision-machined internal components, the 373-4087 injector delivers accurate fuel metering to each cylinder, producing ultra-fine atomization for complete combustion. This results in improved fuel utilization efficiency, stable combustion pressure, and enhanced overall engine power output. The assembly also contributes to reduced exhaust emissions by lowering particulate matter and NOx levels, helping operators meet environmental compliance standards across mining, oil and gas, and power generation sectors.

Built for continuous heavy-load operation, the 373-4087 features high temperature resistance and corrosion-resistant materials, making it well-suited for marine and offshore applications where exposure to harsh conditions is constant. The wear-resistant design extends service life, reducing maintenance frequency and downtime for industrial equipment operators. Whether deployed in emergency standby power systems, offshore energy platforms, or heavy industrial manufacturing facilities, this fuel injector provides the durability and performance consistency required by 3508B, 3512B, and 3516B engine applications worldwide.
