Hitachi excavator Isuzu parts 1-15750197-0 oil supply pump assembly; hand oil pump

Hitachi Excavator 1-15750197-0 Fuel Feed Pump Assembly, specifically designed for precise matching of ISUZU 6BG1 engines in large excavators such as ZX200-5G, ZX210-5G, ZX240-5G, ZX330-5G, etc. It is the core fuel supply component of high-pressure common rail systems (or traditional injection systems), directly responsible for fuel pump oil, pressure establishment, and stable fuel supply to fuel injectors/common rails. Adopting high-strength castings, precision plunger pumps, ZEXEL series fuel injector sealing rings, and high-pressure resistant rubber seals, the pump oil pressure is stable, corrosion-resistant, wear-resistant, and pollution resistant. Perfectly solves faults such as fuel failure to pump, insufficient pressure, slow ignition of fuel pump, insufficient power, increased fuel consumption, high water temperature and oil temperature (highly related to the car holding protection mode after low common rail pressure)
