Abstract
A fuel pipe device for motor vehicles comprising a pipe main body having a plurality of holes formed in its peripheral wall and outward tubular projections each formed around each of the holes integrally with the wall for connecting branch pipes to the pipe main body. The device is produced by a process comprising bulging the peripheral wall of a pipe blank at each of the portions thereof to be connected to the branch pipes to form a tubular protrusion having a closed end, forming a hole in the center of the end closing wall of the protrusion, and bending the remaining portion of the end closing wall around the hole outward by burring flush with the peripheral wall of the protrusion to form the tubular projection. Alternatively, the device is produced by a process comprising forming a hole in a pipe blank at each of the portions thereof to be connected to the branch pipes, and bending the hole-defining portion of the blank outward by burring to form the projection. The device can be fabricated by a smaller number of production steps with greater ease than conventional fuel pipe devices.
