Purpose and function in the fuel system

The presented fuel tank is a component from the Fuel tanks and filler pipes group, responsible for storing petrol and delivering it to other fuel system components. The tank's construction is adapted for use with petrol engines, which is crucial for the material's resistance to fuel, fuel vapors, and temperature fluctuations during operation.

A properly selected fuel tank reduces the risk of leaks, venting issues, and fuel pump malfunctions. Precise fitment for specific body versions and M271 and M272 engine units allows for maintaining factory mounting geometry and hose routing, which facilitates installation and subsequent maintenance.

Construction, parameters, and technical fitment

The tank has been designed for integration with the factory Mercedes fuel system, taking into account space for accessories, hoses, sensors, and mounting elements. The applied design solutions ensure:

• stable fuel retention at various fill levels,
• suitability for use with petrol,
• compatibility with original fuel system components.

The product has an assigned OEM part number and associated interchangeable numbers, which facilitates precise identification via manufacturer catalogs and matching to a specific vehicle. The specified weight of the tank is important both for logistics and for planning installation in the vehicle.

Condition, origin, and service application

The offered fuel tank is a used component, making it an attractive cost-effective alternative to new parts while maintaining the original manufacturer's specifications. This type of component is often chosen by workshops specializing in the Mercedes brand and by conscious users who expect factory fitment and predictable performance during operation.

Replacing the fuel tank is recommended in cases of mechanical damage, corrosion, leaks, or issues with accessory mounting. Using an original tank from the same construction group allows for minimizing adaptation work and reducing vehicle downtime.

Selection by part numbers and technical support

For the correct selection of a fuel tank for a specific Mercedes, it is recommended to use the OEM part number, interchangeable numbers, and vehicle data (VIN, engine type, model year). This helps avoid issues with the compatibility of mounts, connectors, and fuel system accessories. In case of doubt, selection by catalog numbers is the most precise identification method.

To better understand the role of the fuel tank in the entire fuel system as well as diagnostic and maintenance principles, it is worth reading the guide: Fuel system – injectors, pumps, and fuel tank: maintenance and regeneration. The article discusses, among other things, selecting components by VIN and OEM numbers, which is helpful when planning repairs.
