Purpose and function in the fuel system

The ventilation hose in models with an M264 engine running on gasoline is a component associated with the Fuel pumps and level sensors group. Its task is to maintain proper pressure and ventilation in the tank area and auxiliary equipment, which reduces the risk of fuel level reading disturbances and supports uniform fuel supply to the power unit.

A properly functioning ventilation hose helps to reduce:

• fluctuations in fuel level readings during dynamic driving,
• excessive vapor accumulation in the system,
• potential issues with fuel pump operation under varying pressure conditions.

Benefits of using an original Mercedes hose

Using a ventilation hose dedicated to the M264 unit in the W205 body ensures:

• factory geometry and connection diameters, which facilitates installation and minimizes the risk of leaks,
• consistency with the operating characteristics of the gasoline supply system,
• maintenance of parameters specified by the vehicle manufacturer.

For the user, this means more stable fuel system operation, predictable vehicle behavior in daily use, and a lower risk of needing to intervene in the installation again.

Component condition and service application

The offered hose comes from disassembly and is a used original Mercedes component. This type of part works well in:

• maintenance repairs of the fuel system,
• restoring efficiency after leaks or mechanical damage to hoses,
• servicing vehicles where maintaining the original factory configuration is important.

For workshops and users, this means the possibility of an economical repair while maintaining a proper fit for the gasoline system in a Mercedes W205 with an M264 engine.

Integration with the Fuel pumps and level sensors system

The ventilation hose works with elements responsible for pumping fuel and measuring its quantity in the tank. Proper ventilation of the working space promotes:

• stable fuel pump operation at different tank fill levels,
• correct response of the fuel level sensor to changes in gasoline quantity,
• maintenance of the pressure conditions in the system as specified by the manufacturer.

Thanks to this, the gasoline supply system maintains parameters close to factory specifications, which is important for both user comfort and service diagnostics.
