description A fuel-rail assembly 1 comprising an injector 20 having a proximally disposed inlet portion 21 defining an inlet channel 22 and extending along an axial direction A, a fuel rail (10, Fig 1) connected to the inlet portion 21 via an outlet portion 31 that defines an outlet channel 32, a nut element 40 having an inner thread 42 and at least indirectly engaging the outlet portion 31 to transfer an axial clamp force by which a first contact surface 25 of the inlet portion 21 is pressed against a second contact surface 33 of the outlet portion 31 to provide a fluid-tight connection between the inlet channel 22 and the outlet channel 32; In order to enable a wide flow path into an injector while maintaining an easy assembly process of the injector, the fuel-rail assembly 1 comprises an adapter 50 with an axially extending through-opening 51 in which the inlet portion 21 is at least partially received, and with an outer thread 52 that engages the inner thread 42, the adapter 50 at least indirectly pressing against the inlet portion 21 to transfer the clamp force.
