Claims

[Claims for Utility Model Registration] 1. A communication pipe having a linearly extending fuel passage therein, and a plurality of cylindrical sockets for mounting fuel injection valves arranged at predetermined intervals in the longitudinal direction of the communication pipe. The fuel delivery pipe is characterized in that the communication pipe has a double structure of an inner pipe on the inside and an outer pipe on the outside. 2. The fuel delivery pipe according to claim 1, wherein the inner pipe is made of a pipe with a square cross section, and the outer pipe is made with a pipe with a circular cross section. 3. The fuel delivery pipe according to claim 2, wherein each cylindrical socket is seated on the inner pipe as a seal member and is pressed onto the inner pipe by the elastic force of the outer pipe. 4. The fuel delivery pipe according to claim 2, wherein each cylindrical socket is seated on the outer pipe via a seal member and is pressed onto the outer pipe by the elastic force of the inner pipe.
