Denso 295050-0331 Fuel Injector Assembly

The Denso 295050-0331 is a high-pressure electronic common rail fuel injector designed for the Denso HPCR (High Pressure Common Rail) fuel system. It utilizes a solenoid-actuated nozzle assembly (Nozzle Model G3S16) for precise fuel metering and atomization in heavy-duty diesel applications. This injector assembly serves as a direct OEM replacement for Caterpillar part numbers 370-7280 and 3707280, and Perkins part number T409980. It is engineered for compatibility with Caterpillar C4.4 and C7.1 ACERT engines, commonly installed in E-series and F-series hydraulic excavators including the 320, 320F, 323F, 324E, 325F, and 329E models. The component features robust construction for high-cycle durability and consistent injection performance under extreme operating conditions.
