Application and Function in the Fuel System

The described unit combines the functions of a fuel pump and a float module responsible for measuring the fuel level in the tank within a single housing. This design is typical for modern Mercedes models and helps reduce the number of connections, contributing to sealing and stable operating parameters.

The component is dedicated for installation in the fuel tank of W205, W213, and W253 series vehicles, where it works with the factory electrical system and engine control unit. This ensures that the fuel flow characteristics match the engine's requirements and that there is proper cooperation with the speedometer and onboard computer.

Construction and Design Advantages

The fuel pump module with fuel level sensor is based on Mercedes OEM construction, meaning it maintains factory flow rates, operating pressure, and float signal characteristics. The use of original internal architecture reduces the risk of pressure drops under high engine load and minimizes interference in fuel level readings.

Key benefits of using an original module include:

• seamless cooperation with the factory engine control unit and electrical system,
• stable fuel supply across the full range of loads,
• correct fuel level sensor signal characteristics,
• proper geometric fit for the fuel tank in the specific body generation.

Condition, Fitment, and Installation

The component is from a Mercedes vehicle and belongs to the OEM parts group, which facilitates selection for compatibility with a specific body version and engine. Before installation, it is recommended to verify compatibility by OEM number or vehicle VIN to ensure proper fitment of the pump basket, electrical connectors, and fuel lines.

When replacing the fuel pump module, it is advisable to pay attention to:

• the condition of the fuel tank cap seals,
• the cleanliness of the fuel tank interior and fuel lines,
• the correct positioning of the fuel level sensor float,
• secure connection of all electrical connectors and fuel lines.

Benefits of Using an Original Mercedes Fuel Pump

Using an original module from the Fuel Pumps and Level Sensors group to replace a worn-out component restores correct fuel system operating parameters, reduces the risk of starting problems, and prevents uneven engine operation at low fuel levels. At the same time, a properly functioning fuel level sensor provides reliable readings on the dashboard, making refueling planning and vehicle operation easier.
