Common Replacement Reasons

• Hard starting caused by low fuel pressure
• Fuel pressure loss in a direct injection system
• Engine hesitation or stumble under load
• Fuel delivery faults tied to an external high-pressure pump
• Replacement of a worn mechanical pump on the listed Volkswagen or Audi applications

Installation Notes

Confirm the vehicle’s build date and chassis breakpoints before ordering, especially for 2011 Volkswagen CC and 2009 Audi Q7 applications. This pump does not include a gasket, seal, tank seal, or fuel sending unit, so those components must be verified separately during service. Match the OE reference and pump style before installation to ensure the correct external high-pressure fuel pump is selected.

Quality Assurance

Hitachi supplies OE-style fuel system components engineered for direct replacement applications. Verify fitment against the vehicle’s VIN, engine code, and production date before installation.
