Technical Characteristics of the Fuel Line

The line is designed to work with an engine powered by diesel fuel, which entails specific requirements for resistance to pressure, temperature, and the chemical properties of the fuel. The line's construction includes:

• a dedicated routing within the engine bay, minimizing the risk of abrasion,
• adaptation to the operating parameters of the N57 engine's injection system,
• compatibility with factory connectors and mounting brackets.

This allows the line to be integrated into the existing system without the need for modifications or additional adapters.

Component Condition and Benefits of Using BMW Parts

The offered fuel line is a used BMW part, which allows for maintaining factory specifications while reducing costs compared to a new part. Original components from this brand are designed for long-term operation, and their geometry and material are precisely matched to the requirements of the specific engine.

Using a line from the same model family enables:

• maintaining correct fuel pressure and flow in the system,
• preserving compliance with the factory operating parameters of the diesel engine,
• reducing the risk of starting and engine running problems caused by leaks in the lines.

Fuel Line Selection and Compatibility
