Purpose and Function of the Filler Neck Hose

The fuel tank filler neck hose in Mercedes W164 models is responsible for the safe and controlled delivery of fuel from the filler neck to the tank. A properly fitted hose minimizes the risk of leaks, spills, and venting issues during refueling. Using an original part helps maintain the factory flow characteristics and correct routing of the hose relative to the body and tank.

Benefits of Using an Original Mercedes Part

Choosing a filler neck hose specifically designed for the Mercedes W164 series offers:

• Compliance with the original fuel system design,
• Precise fit of the hose's shape and diameter to the vehicle's connectors,
• Reduced risk of stress and cracks caused by improper installation of aftermarket parts,
• Easier diagnosis of potential future leaks.

This ensures the filler neck hose operates stably under typical operating conditions, preventing refueling problems and unwanted fuel odors around the wheel arch or rear bodywork.

Condition and Installation Aspects

The offered hose is a used part, allowing for economical repairs while maintaining original manufacturer specifications. Before installation, a standard visual inspection is recommended, checking the surface for mechanical damage and verifying the mounting points on the vehicle. A correctly fitted filler neck hose facilitates installation in factory brackets and guides, ensuring stable positioning in the space between the body and the fuel tank.

Integration with Wiper System and Bodywork

This product belongs to the Other Wiper Parts category, meaning it is associated with the rear bodywork area, where filler neck hoses and wiper/washer systems are often routed. Proper routing of the filler neck hose is important for:

• Maintaining adequate space for wiring harnesses and washer fluid lines,
• Avoiding collisions with moving suspension components or wheel arch covers,
• Ensuring proper acoustic insulation and vibration reduction.

By using an original hose, users gain greater confidence that all these elements will remain in the configuration intended by the manufacturer.
