I can't locate this item in my FSM, it's on the passenger side if the intake manifold. Looks like vacuum lines connected to it, but one end is broken off and looks like I need a replacement.

Its a vacuum check valve, It lets it pull & hold vacuum.https://www.summitracing.com/parts/r...SABEgIMifD_BwE

Think is is part of the HVAC vacuum operation system.

I stumbled upon this a very long time ago and I believe you have '93. Here's routing and GM Part # for you. I would imagine the part # has been replaced and there's very generic used most often. An OE/GM at the time I believe would have come with the elbow connector. I'm quite sure routing is correct.

That seems to be where they always break. Mine did also. Dan

pretty much a generic part - try dorman #47150 - about $5 or $6 at just about any parts house. fairly sure a GM OE parts are discontinued, but they do show up on fleabay from time to time - i'm thinking they're running about $20. try part number 14056648.



BTW - running the dorman part on my 85 - no issues.
