Description
The Leak Fuel Line (Part No. A651070013264) is a genuine OEM Mercedes-Benz fuel return (leak-off) line designed to safely carry excess fuel from the injectors back to the fuel system.
This line plays a critical role in maintaining proper fuel pressure, injector efficiency, and smooth engine performance, especially in common-rail diesel engines. Manufactured from fuel-resistant, high-temperature materials, it provides reliable sealing, flexibility, and long-term durability under demanding engine bay conditions.
Replacing cracked, brittle, or leaking fuel lines prevents fuel loss, air entry, poor idling, and starting issues, ensuring optimal fuel system operation and safety. OEM quality guarantees precise fitment and leak-free connections.
