hello, on the upper part of the lower intake manifold, there is a a metal vac line or something. that connects to the manifold by four bolts, two on the side and one in the front and rear of the lower intake manifold. at least it looks like the lower manifold. i haved looked everywhere, and the only place i can find it in is the mazda parts list. no listing, on the parts list for that rail.

need any info, thanks
