Purpose and function in the fuel system

The described fuel pump and level sensor unit is designed for installation on the left side of the fuel tank in the Audi S8 D3 generation with a petrol FSI engine. In this configuration, it is responsible for:

• stable fuel supply to the engine at the appropriate operating pressure,
• continuous measurement of the fuel level in the left tank chamber,
• cooperation with the dashboard and vehicle electronics regarding fuel level indications.

Thanks to its factory fit for the specific model and fuel type, this component contributes to a coherent, predictable fuel system, which is particularly important in high-performance petrol engines such as the 5.2 FSI.

Construction and installation fit

The left fuel pump module with level sensor is designed as a complete unit for installation in the Audi S8 D3 fuel tank. The design includes:

• dedicated placement on the left side, consistent with the tank geometry,
• integrated fuel level sensor compatible with the factory instrument cluster,
• adaptation for operation with petrol in an FSI system.

This solution reduces the need for installation modifications and allows for the preservation of the original fuel system operating characteristics, which is beneficial for both reliability and service diagnostics.

Benefits of using the original module

Using the original left fuel pump module with level sensor in an Audi S8 D3 brings a number of practical benefits:
