Fuel injector, fuel rail and injection system with the fuel rail and the fuel injector

The invention describes a fuel injector (1), a fuel rail (22) and a fuel injection system with a fuel rail and a fuel injector that are connected by a fuel tube (4). The fuel tube is flexible and elastic without changing its diameter. Using the flexible and elastic fuel tube different distances between the fuel rail and a cylinder head or a misalignment between a fuel connecting tube of the fuel rail that is connected with the fuel injector and an injection opening in a cylinder head will be compensated.
