Purpose and function in the fuel system

The presented tank belongs to the Fuel tanks and filler pipes category and is designed to work with the gasoline engine in the Mercedes C-Class W204 generation in the C63 AMG version. It is responsible for the safe storage of fuel, its stable delivery to the pump, and proper integration with fuel system accessories, sensors, and lines.

The tank's construction is adapted to the specifics of the sporty AMG variant, where maintaining the correct fuel level during dynamic driving, braking, and acceleration is crucial. The 66-liter capacity allows for comfortable operation of a high-power vehicle, reducing the frequency of refueling while maintaining an appropriate operating reserve.

Construction, material, and performance parameters

The fuel tank has been designed as a component that works with the gasoline supply system, taking into account safety requirements and resistance to typical operational loads. The design provides for integration with the factory filler neck, fuel lines, and mounting elements characteristic of the W204 platform.

An important parameter is also the specific total weight of the component, which is significant when planning assembly, disassembly, and service logistics. The tank is prepared to work with factory body mounts, which facilitates its installation in the vehicle without the need for structural modifications.

Condition, fitment, and service application

The item comes from a used vehicle, making it an attractive solution for users looking for original Mercedes parts with a reasonable cost-to-quality ratio. A used fuel tank is particularly useful in the case of post-accident repairs, corrosion, or mechanical damage to the factory tank, as well as during comprehensive vehicle restoration.

Thanks to the preservation of factory geometry and mounting points, the fitment to the W204 C63 AMG body is precise, which minimizes the risk of leaks and assembly problems. Using an original component allows for maintaining compliance with the manufacturer's service documentation and facilitates future diagnostics.

Compatibility, identification, and selection by part numbers

The tank is a component dedicated to a specific model configuration, therefore, it is recommended to verify it by OEM number, interchangeable numbers, and vehicle data (VIN) during selection. The presence of assigned reference numbers facilitates the work of workshops and sellers, ensuring proper fitment to the specific body version and fuel system.

In service practice, it is also important to consider the type of fuel – in this case, it is a gasoline system – which is significant for compatibility with the pump, lines, and accessories. Using the correct tank reduces the risk of problems with venting, fuel level indication, and engine operation.

Technical support and additional information
