Purpose and function in the fuel system

The described fuel filler neck pipe is part of the Fuel tanks and filler pipes category, responsible for safely delivering diesel fuel to the tank in the Mercedes Citan W415. The design of the hose is adapted to the vehicle's body geometry, ensuring proper gradients, bending radii, and the correct position of the connectors relative to the filler and the tank.

The component works in conjunction with the tank ventilation system, minimizing the risk of fuel backflow during refueling and reducing the formation of air pockets. A correctly selected fuel filler neck pipe helps maintain stable operating conditions for the entire fuel system, which translates into consistent fuel delivery to the diesel engine.

Compatibility with Mercedes Citan W415 Diesel

The pipe has been designed specifically for use in the Mercedes Citan W415 generation with a Diesel engine, which means it is compatible with factory mounts, brackets, and body covers. The original geometry of the hose facilitates installation at factory mounting points without the need for modifications or adjustments to diameters.

By using a dedicated solution for a specific body version and fuel type, proper connection tightness and resistance to typical operational loads—such as vibrations, temperature changes, and contact with diesel fuel—are maintained. This is particularly important in commercial vehicles, where the fuel system operates under variable conditions and increased loads.

Characteristics of the used OEM component

The offered fuel filler neck pipe is a used original Mercedes component, which in practice means it retains the factory material and dimensional specifications. Unlike many aftermarket replacements, the OEM component is designed with long-term resistance to diesel fuel, moisture, and road debris in mind.

A used element of this type is a good solution for service repairs when the priority is proper fitment with the existing fuel tank, external filler, and underbody covers. This reduces installation time and the risk of leaks resulting from inaccurate hose shape matching.

Benefits of using a dedicated fuel filler neck pipe

• Factory fitment for the body and fuel tank of the Mercedes Citan W415.
• Adapted for use with diesel fuel, taking into account the properties of Diesel fuel.
• Stable hose routing, reducing stress and the risk of cracks.
• Reduced risk of fuel leaks and refueling issues.
• Time savings during installation due to the preservation of original geometry.

Technical support and additional information

To select the correct fuel filler neck pipe for a specific equipment version and model year, it is recommended to use catalog data and manufacturer markings. The product has assigned interchangeable numbers, which facilitates verifying compatibility with other references used in the Mercedes fuel system.

If you are planning a comprehensive repair or upgrade of the fuel supply area in your Mercedes and need other components from the same group, such as filler hoses, connectors, or mounting elements, check the available parts in the Mercedes fuel tanks and filler pipes category.
