Application and function in the fuel system

This fuel line is dedicated to the 2.0 TDI engine with the CNHA code in Audi A4 B8 and Audi A5 8T models. It is responsible for precise fuel routing within the engine compartment, while maintaining the appropriate operating pressure and resistance to vibrations, temperature, and typical operational loads. Thanks to its factory geometry and proper profiling, the line fits according to the original installation route, which minimizes stress, friction against adjacent components, and the risk of abrasion during long-term engine operation.

Construction, fitment and installation

As a component from the Lines, hoses and pipes group, the fuel hose has been designed for the specific architecture of the Audi A4 B8 / A5 8T engine compartment with the 2.0 TDI CNHA unit. The appropriately selected working diameter, shape, and mounting points allow for installation in place of the factory line without the need for system modifications. The line works with standard connectors and brackets, which facilitates the mechanic's work and shortens service time. Maintaining the original fuel routing path helps to keep proper cooling of adjacent components and reduces the risk of local overheating.

Benefits of using an original Audi line

Using a fuel line dedicated to a specific engine and body configuration allows for maintaining the factory parameters of the fuel supply system. The appropriate stiffness and flexibility of the line reduce the transmission of vibrations to accessory components, and the proper chemical resistance ensures material stability in contact with diesel fuel. For workshops and users, this means:

• a secure fit to the fuel system without the need for custom adapters,
• maintaining factory-level tightness and system safety,
• easier diagnostics of potential fuel supply-related faults.

Component condition and service application

The fuel line is offered as a used part, which allows for an economical repair of the fuel system while maintaining the manufacturer's original specifications. This type of component is particularly useful when replacing damaged, brittle, or leaking lines in vehicles used intensively, where quick restoration of the fuel system's efficiency is crucial.

System expansion and selection of other components

If you are planning a comprehensive repair or upgrade of the fuel system area in your Audi and need other elements from the same group, such as flexible supply hoses, rigid guide pipes, or return lines, check the available parts in the Audi lines, hoses and pipes category.
