Purpose and technical function

The presented fuel filler cap is designed as a component that seals the fuel tank neck in Mercedes R170, W202, W208, and W210 series cars. Its task is to tightly secure the fuel system against external contaminants and limit fuel evaporation, which is important for both operational safety and engine performance stability.

The original construction ensures proper cooperation with the factory thread and filler socket, which minimizes the risk of leaks. As a result, the cap is a functional addition to the fuel system, maintaining the parameters specified by the vehicle manufacturer.

Construction and workmanship

The cap is finished in black, allowing for an aesthetic match to most factory fuel filler flaps in Mercedes models. The handle geometry allows for a comfortable grip and efficient tightening and loosening, even when wearing work gloves.

The element belongs to the Fuel filler flaps and caps group, which means its construction is adapted to work in an environment exposed to contact with fuel, temperature changes, and typical operational loads. The used OEM part retains factory mounting dimensions, which facilitates direct replacement without the need for modifications.

Condition and vehicle fitment

The product is offered as a used item, which in practice means it comes from disassembly and may show signs of normal wear while maintaining the functionality required for further use. For proper selection, it is recommended to verify compatibility by the OEM number or interchangeable numbers in relation to the specific vehicle model and year.

Due to its factory origin, the cap is intended for use with the original Mercedes fuel system, which reduces the risk of fitment problems typical of universal aftermarket replacements.

Benefits of using an original fuel filler cap

• Fuel system compatibility – construction compliant with the vehicle manufacturer's requirements.
• Stable closure of the filler neck, promoting the maintenance of system tightness.
• Aesthetic, black appearance matched to the factory Mercedes styling.
• Possibility of direct replacement of a worn or damaged cap without additional modifications.

To better understand the role of this component in the entire fuel supply system, it is worth reading the guide on diagnostics and operation of the fuel system – it is discussed in detail in the article Fuel system – injectors, pumps, and fuel tank: maintenance and regeneration, where you will find practical tips on selecting parts by OEM numbers and the principles of proper maintenance.
