Purpose and Role in the Fuel System

In a gasoline engine, the fuel rail plays a crucial role in distributing fuel to individual injectors. For M264 engines in the Mercedes W205, it is responsible for:

• maintaining stable gasoline pressure throughout the fuel system
• uniform supply to all cylinders, which reduces the risk of knocking and uneven running
• cooperation with precise injectors electronically controlled by the engine control unit

Thanks to its carefully designed flow channels, the fuel rail supports efficient mixture combustion, which is important for both driving dynamics and fuel economy.

Construction and Fit for the M264 Engine

The Mercedes W205 M264 Fuel Rail A2640701000 has been specifically developed for the M264 engine architecture, taking into account the placement of injectors, fuel lines, and engine accessories. This means:

• factory mounting points matched to the M264 engine head
• geometry ensuring correct injector positioning relative to the combustion chambers
• compatibility with the gasoline fuel system used in this engine series

This precise fit minimizes the need for any modifications and allows for installation in accordance with the manufacturer's service documentation.

Benefits of Using an Original Fuel Rail

Using an original fuel rail in the injector nozzles category for the Mercedes W205 with an M264 engine offers a number of practical benefits:

• stable engine operation due to uniform supply to all cylinders
• improved idle quality and performance under changing loads
• maintenance of factory fuel consumption parameters, supporting emissions standards
• easier fuel system diagnostics, as the component matches the manufacturer's specifications

This solution is particularly recommended for issues with gasoline injector operation, uneven engine running, or after repairs to the fuel system.

Condition, Installation, and Service Application

The offered fuel rail is a used part, making it an attractive option for servicing vehicles used intensively or with higher mileage. In practice, this means the possibility of:

• optimizing repair costs while maintaining original construction
• replacing a damaged fuel rail without affecting other system components
• restoring correct gasoline supply to the M264 engine without installation modifications

Installation should be performed according to Mercedes service procedures, ensuring cleanliness of the fuel system and proper tightening torque for the fasteners.
