Mercedes W906 Fuel Pump Diesel Sender Delivery Control Unit Module A9064703200

Mercedes W906 Fuel Pump Diesel Sender Delivery Control Unit Module is a specialized fuel system component designed for Mercedes diesel vehicles. It combines the function of supplying diesel fuel to the engine and precise fuel level measurement in a single housing, ensuring stable engine operation and reliable readings on the instrument cluster. A used component from this group is a sensible choice for servicing vehicles used intensively, where functionality, fitment, and cost control are key priorities.

Purpose and function in the fuel system

The described assembly belongs to the Fuel pumps and level sensors group, responsible for both transporting diesel fuel from the tank and transmitting information about its quantity to the vehicle's electrical system. In Mercedes W906 vehicles, a properly functioning pump with a float and level sensor is crucial for:

• maintaining appropriate supply pressure at subsequent stages of the fuel system,
• stable operation of the diesel engine without interruptions in fuel supply,
• accurate fuel level indication on the dashboard,
• correct operation of onboard systems that utilize fuel quantity information.

The integrated solution, combining the pump, float, and sensor, reduces the number of connections and potential leak points, which promotes trouble-free operation in the demanding conditions of commercial vehicle use.

Compatibility with diesel engines

The element has been designed to work with the Diesel supply system, which means it features appropriate hydraulic and material construction adapted to the properties of diesel fuel. As a result, it maintains resistance to typical operational loads, such as:

• continuous operation in varying fuel and ambient temperatures,
• contact with refining additives and biocomponents in the fuel,
• vibrations transmitted from the vehicle's body and chassis.

Selecting a fuel pump with a float and level sensor dedicated to a specific fuel type minimizes the risk of premature wear and problems with starting or uneven engine operation.

Characteristics of the used component

The offered item is in used condition, which in practice means it comes from a vehicle disassembly and has been previously operated. This type of part is particularly attractive when servicing older Mercedes W906 models, where the priority is to maintain proper functionality while reducing repair costs. In the case of fuel pumps and level sensors, it is important that:

• the housing and connection ports remain airtight,
• the float mechanism moves freely throughout its full operating range,
• the level sensor transmits a stable signal to the vehicle's electrical system.

Choosing an original component from disassembly allows for maintaining factory fitment to the fuel tank and electrical harness, which facilitates installation and reduces the risk of compatibility issues.

Benefits of using an original fuel pump with a float

Using a fuel pump assembly integrated with a float and level sensor in a Mercedes W906 translates into a number of practical service and operational benefits:

• Coherent design – a single housing for the pump, float, and sensor simplifies installation and limits the number of connections.
• Factory fitment – geometry and mounting points correspond to the solution used in series-production Mercedes vehicles, which promotes trouble-free installation.
• Stable engine supply – a properly functioning pump supports uniform operation of the diesel engine across the full load range.
• Reliable fuel level reading – a functional float and level sensor reduce the risk of incorrect readings on the instrument cluster.

An element configured in this way is particularly useful when replacing a damaged assembly in vehicles used intensively in local and long-distance transport.

Technical support and additional materials

When selecting used fuel system and electronic components, it is worth using reliable sources of knowledge.
