A fuel distributor for supplying fuel to injection valves for internal combustion engines includes a hollow manifold having a plurality of branch bores disposed radially therethrough. A plurality of branch lines are operably connected with a manifold at the branch bores by adapters. The adapters have either a one-piece deep-drawn construction or a one-piece extruded construction, and include a mounting flange that conforms to the outer contour of the manifold and joins the adapter to the exterior of the manifold, and a neck portion that closely receives and securely mounts therein the end portions of the branch lines.
