Abstract
A main tube provided with a channel is mounted in a fuel rail and has a peripheral wall. One or more holes extend vertically through the peripheral wall and are in communication with the channel. Each hole forms a dished seat portion having either a staircase-like cross section or an inclined surface. The enlarged portion is formed near one end of the branching connector and extends to the inclined wall toward the front end. A connection head portion is formed at the front end of the enlarged portion. The connection head portion totally conforms in cross-sectional shape with the seat portion. The head portion is brought into abutting engagement with the seat portion. The engaging portions of the abutting portions are brazed and connected together.
