Product Details

What It Helps Address

  • Hard starting related to low fuel pressure
  • Fuel delivery faults in direct injection systems
  • Engine hesitation during acceleration
  • Rough idle caused by inconsistent high-pressure fuel supply
  • Check engine light conditions tied to fuel pressure performance

Installation Notes

Confirm the vehicle’s fuel system and OE part number before installation. This Bosch 66814 pump is an internal, electric high pressure fuel pump with one outlet, so the replacement should match the original configuration. Because gaskets and mounting hardware are not included, reuse only serviceable components or source the correct seals and hardware separately as required by the application.

Quality Assurance

Bosch manufactures this pump to rigorous OE-level standards and tests it to the same quality expectations used for original equipment fuel pumps. That production approach supports reliable performance and long service life in direct injection applications.
