Purpose and function in the fuel system

The presented tank belongs to the Fuel tanks and filler pipes category and is structurally adapted to the chassis architecture of the Mercedes CLK W203/C209. It is responsible for the safe storage of petrol, cooperation with the fuel pump, and maintaining the correct pressure and flow throughout the entire fuel supply system.

In vehicles with a petrol engine, it is crucial to maintain the tightness and proper venting of the tank to reduce the risk of power drops, starting problems, or engine control unit errors. This tank model has been designed specifically with these operational requirements in mind.

Compatibility and OEM identification

The component is dedicated to Mercedes cars from the CLK family, which makes it easier to select parts based on the OEM number and interchangeable numbers available in the technical specification. This allows for precise verification of compatibility with your specific vehicle, minimizing the risk of purchasing a non-matching component.

In practice, this means that the tank has been designed for specific mounting points, chassis geometry, and fuel line layout, which translates into trouble-free installation and proper cooperation with factory equipment.

Technical and operational characteristics

The 62-liter tank provides an adequate fuel reserve for petrol units, supporting driving comfort on longer routes and reducing the frequency of refueling. The construction is adapted to work with the compressor system, which is important for turbocharged engines sensitive to fuel pressure fluctuations.

The most important functional features include:

• fitment to the factory mounting system in the Mercedes CLK W203/C209,
• adaptation for petrol operation,
• compatibility with original fuel system lines and equipment,
• maintenance of parameters required by the vehicle manufacturer.

Thanks to this, the tank will work well both for standard replacement of a worn-out element and for repairs after mechanical damage within the chassis area.

Condition, advantages of using a used part, and installation

The offered item is in used condition, which is a favorable compromise between cost and maintaining the manufacturer's original design. Unlike many aftermarket replacements, the factory fuel tank retains its original geometry, wall thickness, and nozzle placement, which facilitates installation and reduces the need for modifications.

Choosing an original, used fuel tank is particularly sensible for repairs where compliance with factory service documentation and predictable long-term performance are important. A correctly selected tank helps avoid problems with leaks, improper venting, or collisions with other chassis components.

Technical support, selection, and additional knowledge

When selecting a fuel tank for a specific engine version and model year, it is worth using the OEM number and interchangeable numbers visible in the technical specification, as well as data from the manufacturer's catalogs. Proper identification by VIN or OEM helps avoid returns and speeds up the repair process.

If you are planning a comprehensive repair or upgrade of the fuel system area in your Mercedes and need other elements from the same group, such as filler hoses, vent pipes, or additional mounting elements, check the available parts in the Mercedes Fuel tanks and filler pipes category.
