ABSTRACT:
An internal combustion engine intake manifold has a wall separating internal manifold space from an external space. The body of a purge valve for purging fuel vapors from an evaporative emission space of a fuel storage system for an engine is disposed in the external space mounted on the wall such that a portion of the purge valve body that contains an outlet port confronts the wall, and the portion of the wall confronted by that portion of the purge valve body contains an opening through which the outlet port communicates with the internal manifold space. The outlet port may be a nipple which passes through the opening in the manifold wall to communicate the outlet port with the internal manifold space.
