Purpose and technical function

The cap is designed for Mercedes vehicles equipped with diesel engines, where a tight seal of the filler neck is crucial. It is responsible for maintaining proper conditions in the fuel tank, reducing diesel evaporation, and protecting the system from external contaminants.

Thanks to its fitment for a specific model group, the cap works with the factory filler flap, maintaining correct geometry and operating ergonomics. This solution is particularly important in modern diesel fuel systems, where stable pressure and fuel purity affect the performance of injectors and pumps.

Color scheme and fuel identification

The element is made in Red, which serves both a visual and practical function. The contrasting color makes it easier to distinguish the cap intended for diesel from other elements in the filler compartment, which helps minimize the risk of errors during refueling.

Clear marking of the Diesel fuel type is particularly useful in fleet vehicles or those used by multiple drivers, where clear identification of service and maintenance points is important for safety and proper vehicle operation.

Identification parameters and fitment

The cap has a dedicated OEM part number, which facilitates unambiguous verification of compatibility with a specific body version and fuel system. Additionally, interchangeable numbers are available, allowing for quick comparison with markings used in service catalogs and parts selection systems.

In the product description, you will also find the SKU marking, useful for order processing and communication with the sales department. Information about the condition of the item allows you to consciously choose the part for the planned scope of repair or replacement.

Practical application and operation

Replacing the fuel cap is recommended in situations where the existing element shows signs of wear, mechanical damage, or problems with closing. A functional cap helps maintain stable operating conditions for the fuel system, which is important for the longevity of injectors, the pump, and other components.

To better understand the impact of filler tightness on the entire fuel system, it is worth reading an article describing the construction and maintenance of modern diesel fuel systems – a detailed discussion can be found in the material Fuel system – injectors, pumps, and fuel tank: maintenance and regeneration.
