Purpose and function in the AdBlue system

The described AdBlue tank pump assembly is factory-designed to work with the exhaust gas treatment system in Mercedes commercial vehicles equipped with SCR technology. This component is responsible for:

• pumping the AdBlue agent from the tank to the dosing system supply lines,
• maintaining stable flow parameters under various engine operating conditions,
• cooperating with the exhaust emission control electronics.

As a result, the vehicle remains compliant with exhaust emission standards, and the driver avoids power limitations and error messages associated with improper AdBlue system operation.

Pump assembly construction and tank integration

The complete pump installation in the AdBlue tank within the Fuel tanks and filler pipes category means that the user receives an integrated sub-assembly that can be installed in place of the factory component. This type of solution:

• simplifies the service process – the entire assembly is replaced, rather than individual components,
• reduces the risk of leaks and system venting problems,
• ensures correct fitment to factory mounts and lines.

This approach is particularly beneficial for vehicles in intensive use, where a quick return to service and minimizing downtime is essential.

Benefits of using an original Mercedes component

Using an original Mercedes sub-assembly in the AdBlue system translates into a number of practical benefits:

• precise fitment to the fuel and emission installation of the specific W907/W910 vehicle generation,
• maintenance of operating parameters specified by the vehicle manufacturer,
• reduced risk of engine control unit errors related to incorrect pressure or agent flow.

For fleets and professional users, this means stable operation of the exhaust gas treatment system and a reduction in unplanned service visits.

Condition, selection, and practical application

The item is offered as a used part, which allows for lower repair costs while maintaining the original design and compatibility with the vehicle's factory system. Before installation, it is recommended to verify compatibility by OEM number and vehicle model to ensure a correct fit for the specific version of the AdBlue system.

In practice, replacing the complete AdBlue tank pump assembly is recommended in situations where there are problems with pressure build-up, SCR system errors, or recurring messages regarding dosing system faults. Installing an original sub-assembly allows for restoring proper system operation and avoiding further damage associated with improper emission system performance.

Service expansion and additional materials

If you are planning a comprehensive repair or upgrade of the fuel and AdBlue supply zone in your Mercedes and need other elements from the same group, such as tanks, lines, or filler pipes, check out the available parts in the Mercedes Fuel tanks and filler pipes category.

To better plan the diagnostics and service of the supply system, it is worth consulting the guide describing the construction and operation of the entire system – from injectors and pumps to the fuel tank and associated components. A detailed discussion can be found in the article "Fuel system – injectors, pumps, and fuel tank: maintenance and regeneration", which facilitates part selection by OEM number and VIN, and helps understand the relationships between individual sub-assemblies.
