Purpose and Function in the Fuel System

The fuel supply hose is dedicated to Diesel N47N engines fitted in BMW E90, E91, E92, and E93 models. It is responsible for safely delivering diesel fuel to the injection system components, which directly impacts the engine's stable operation, running smoothness, and correct fuel metering.

A properly selected fuel hose minimizes the risk of leaks, pressure drops, and starting problems, which is particularly crucial in modern diesel engines with precise fuel injection control.

Benefits of Using an Original BMW Hose

Using an original fuel supply hose in an N47N engine allows you to maintain:

• factory fuel line routing in the engine bay,
• correct fitment to spigots and mounts,
• consistency with other fuel system components.

This ensures an organized installation without the need for modifications, and the fuel system retains the parameters specified by the manufacturer. This solution is particularly beneficial for repairs after fuel leaks, replacement of injection components, or restoring the car to its factory specifications.

Characteristics of a Used Part

The offered fuel hose is a used part, sourced from disassembly. This type of component allows for economical repairs while maintaining the original BMW construction, which is especially important for complex fuel systems in diesel engines. A used component with preserved geometry and connections is a good choice when aiming for compliance with the factory design and reducing service costs.

Technical Selection and Compatibility

The hose has been specifically designed to work with the N47N engine fuel system in E90, E91, E92, and E93 body styles, simplifying technical part selection. Relevant part numbers and interchangeable numbers are available in the specifications section, allowing you to verify compatibility with your specific vehicle configuration before installation. This minimizes the risk of incorrect fitment and the need for re-replacement.
