Hi guy's, quick question, what is the part # to the 90* small hose coming from the PCV valve to the metal hose and if not available what size vacuum hose can I use, thanks in advance.

See if this helps. Be sure to read the note in the lower right corner.

Thanks Injuneer, I just need that small rubber hose that connects to the PCV valve to the metal hose. It doesn't make sense to spend 50 dollars just for the whole hose just for the little hose that I need. Do you know the size of that particular hose, maybe I can use some vacuum hose to compensate.

Probably a 5/16 or 3/8 piece of fuel hose will get the job done.

Are the 2 ends of the rubber elbow the same diameter or different diameters? I can't look at my 94, because it doesn't use the metal pipe or the vacuum source under the TB. If same size, a piece of vacuum hose that fits over the metal tube, and a plastic elbow can be cobbled up to match. If the PCV end of the rubber elbow is larger than the pipe end, try various spark plug boots to find a match, like people are now doing with the EVAP connection on the throttle body.

If you are referring to the hose that is located under the throttle body, it is 11/32" inside diameter on my 95 Z28. GMPart #12551389

If you read carefully, he is looking for the elbow on the other end of the pipe, "from the PCV valve to the metal hose" (repeated in two posts). The Shoebox link I gave him showed the part # for elbow under the throttle body, so he has already seen that and from his response, that's not what he is looking for.

He hasn't signed back into the site since his last post on 10/18, so we may never know.
