I totally over looked your question about what it is...

its got to be some kind of one-way valve or pressure valve (spring inside)

Have a look at that emissions sticker under the hood, hose diagram or maybe get a look at the factory manual. Without any diagrams for your car I really can't tell by the picture, I have only been under the hood of a Metro a few times many years ago.

good luck

I am not trying to save the planet, just trying to hurt it a little less
