Installation Notes and Tips

Inspection on vehicle is required for many listed applications. If necessary, the high-pressure pipe to the rail and any required adapters must be obtained from the vehicle manufacturer. Verify engine code, fuel system configuration, and OE part number before installation. Because this is an internal electric pump, confirm the mounting location and fuel line routing match the vehicle’s original setup.

Quality Assurance

Bosch manufactures this pump using the same production standards applied to its original equipment fuel pumps, then tests it to rigorous quality requirements before release. That OE-level process supports reliable operation in direct injection applications such as Audi Q3, Audi A3, Volkswagen Jetta, and Volkswagen Tiguan.

This part fits 70 vehicles

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
