To provide a mounting structure for a fuel distributing pipe, capable of using an intake manifold block in common.

A reinforcing plate 2 is mounted to a mounting boss 4 formed near a branch of an intake manifold block 3, and a fuel distributing pipe 1 is mounted to a mounting seat part 17 formed on the reinforcing plate 2, and a mounting structure of the fuel distributing pipe 1 is constituted. By this structure, even in a case where the fuel distributing pipe 1 can not be installed on the intake manifold block 3 caused by a change of specification of an engine, the fuel distributing pipe 1 can be mounted and installed on the mounting seat part 17 formed on the reinforcing plate 2 by changing the reinforcing plate 2, and the intake manifold block 3 can be used in common.
