Purpose and Function in the Fuel System

The fuel injector line for Mercedes W169 and W245 is responsible for precisely delivering fuel under high pressure to the injectors. A correctly selected component minimizes the risk of pressure drops, leaks, and engine malfunctions, which translates to stable engine operation.

Using a line that conforms to factory specifications is particularly important in modern injection systems, where tolerances are tight, and each element affects fuel delivery, emissions, and component wear.

Benefits of Using an Original Mercedes Line

Choosing an original injector line from this series offers primarily:

• compliance with the original fuel system design,
• a secure fit for engine ports and mounts,
• appropriate resistance to operating pressure and temperature,
• reduced risk of uncontrolled fuel leaks.

This allows the line to be used both as a replacement part during standard repairs and during comprehensive injection system overhauls, where consistent performance parameters are crucial.

Item Condition and Service Application

The offered line is a used original part from disassembly. This type of part is suitable for vehicles where maintaining proper fuel system operation is a priority, while also reducing costs compared to purchasing a new component. A used injector line can be a sensible choice for routine maintenance repairs when other system components are in good technical condition.

Injector Line Selection and Compatibility

To correctly select the line for a specific engine version, it is advisable to verify the part numbers in the vehicle's service documentation and compare the injection system configuration. The product has an OEM part number and assigned replacement numbers, which facilitates identification of compatibility with a given engine and car year. This approach reduces the risk of installing an incorrect part and speeds up the service process.
