Product Details

The Bosch 642-078-01-49 is a common rail fuel pressure control valve designed for diesel fuel injection systems. This precision-engineered component mounts directly on the fuel rail and plays a critical role in maintaining optimal fuel pressure throughout the common rail system.

Key Features:

  • Control valve design for precise fuel pressure regulation in common rail systems
  • Manufactured by Bosch to OEM specifications for reliable performance
  • Direct replacement for Mercedes-Benz OEM part number A6420780149
  • Bosch part number 0281002794 cross-reference
  • Mounts at the fuel rail with integrated electrical connector
  • Maintains consistent fuel pressure for optimal engine performance and fuel efficiency

This fuel pressure control valve works with the engine control module to regulate and maintain commanded rail pressure in common rail diesel fuel injection systems. Important: The valve uses a knife-edge seal design that creates a metal-to-metal seal with the fuel rail and must be replaced if removed, as the seal cannot be reused.

Cross-Reference Numbers: Mercedes-Benz A6420780149, 6420780149, A642078149, Bosch 0281002794
