Purpose and Function of the Fuel Pump Mounting Nut

The fuel pump mounting nut is responsible for pressing the pump housing against the fuel tank flange and maintaining the appropriate seal of the connection. In Mercedes W204 and W212 vehicles, this component operates in a demanding environment, exposed to temperature changes, vibrations, and contact with fuel vapors. Therefore, using the correct component is crucial for:

• maintaining the fuel system's integrity,
• stable seating of the pump module in the tank,
• reducing the risk of leaks and fuel odor around the tank,
• correct positioning of the pump relative to sensors and lines.

Benefits of Using an Original Mercedes Nut

Using a nut originating from the Mercedes group allows for the preservation of parameters intended by the vehicle manufacturer. In practice, this means:

• precise fit to the fuel tank thread and flange,
• correct distribution of clamping forces around the entire mounting perimeter,
• compatibility with the factory fuel pump module used in W204 and W212,
• reduced risk of thread damage or flange deformation during installation.

For workshops and users, this translates to easier installation, predictable component behavior during operation, and stable fuel supply system performance without the need for compromise solutions.

Item Condition and Service Application

The offered nut is a used part from disassembly, making it an attractive cost-effective alternative while maintaining the original manufacturer's specifications. It is suitable for replacing a worn or damaged nut, as well as for comprehensive service work related to:

• fuel pump replacement,
• fuel module refurbishment,
• tank repair after a collision or mechanical damage,
• diagnosing leaks around the pump flange.

Selection by OEM Number and Technical Support

The selection of the correct fuel pump mounting nut for a specific Mercedes W204 or W212 version should be based on the OEM number and vehicle data. To facilitate the identification process, it is advisable to use practical tips for working with catalog numbers and manufacturer markings – this is described in detail in the guide: how to select the correct car part by OEM number and vehicle data. This minimizes the risk of errors and speeds up the service process.
