Purpose and function in the fuel system

The described fuel pump with a level sensor unit has been designed specifically for the sports versions of the Mercedes W204 C63 and W212 E63 AMG, where the fuel system operates under increased load. The component is responsible for both continuous fuel delivery to the fuel rail and transmitting the current fuel level signal to the vehicle's electronics.

Combining the pump and sensor into a single unit reduces the number of connections in the tank, which promotes reliability and facilitates diagnostics. Using the original Mercedes design allows for maintaining factory flow characteristics and proper interaction with the engine control system.

Construction of the fuel pump and level sensor assembly

The set includes an integrated fuel pump module and a level sensor (float with a measuring track), forming a single assembly mounted in the tank. This configuration ensures:

• stable fuel supply during dynamic driving characteristic of AMG versions,
• precise fuel level reading across the entire tank range,
• proper cooperation with the factory gauge on the dashboard,
• preservation of the original mounting geometry in the tank.

By maintaining the factory design, the system maintains appropriate flow parameters, which is particularly important under high engine loads and frequent driving in sport mode.

Benefits of using an original Mercedes fuel pump

Choosing an original fuel pump and level sensor assembly for C63 and E63 AMG models helps reduce the risk of problems typical of replacements, such as unstable pressure, incorrect fuel level readings, or interference with the engine controller. Using a component from the same design line as the factory element means:

• secure fit to the fuel tank and existing electrical installation,
• preservation of factory fuel system operating parameters,
• lower risk of error codes in the vehicle's diagnostic systems,
• consistency with other fuel system components in AMG versions.

This is particularly important in high-power cars, where fuel supply stability directly translates into performance and operational safety.

Product characteristics and practical application

The presented element belongs to the Fuel pumps and level sensors group, which means it combines the functions of supply and measurement. In practice, this allows for the simultaneous replacement of a worn-out pump and a faulty sensor without the need to interfere with several separate sub-assemblies. For workshops and users, this means shorter service time and a lower risk of leaks or wiring harness problems.

The product comes from the Mercedes brand, which facilitates selection based on compatibility with a specific equipment version and vehicle year. In case of doubts regarding compatibility, it is worth using the OEM number or interchangeable numbers visible in the technical specification to match the element to the specific car configuration.

Condition, installation, and selection by numbers

The element is offered in used condition, which allows combining original build quality with an attractive price compared to a new module. Before installation, a standard check of the vehicle's fuel system is recommended, including hose tightness and the condition of electrical connectors, to fully utilize the potential of the applied component.

Selection by OEM part number and interchangeable numbers allows for verifying compatibility with a specific engine and equipment version. This is particularly important in the case of AMG models, where the fuel system may differ from standard variants of a given body style.

If you are planning a comprehensive repair or upgrade of the fuel supply area in your Mercedes and need other elements from the same group, such as pump modules, level sensor assemblies, or complete tank inserts, check the available parts in the Mercedes fuel pumps and level sensors category.
