I kept herring something dangling in the front right wheel area and I seen this hooked up to something just loose.

Its shaped like a relay but I cant make out whats sticking off either end of it.

cant see the pictures too well - any part #s on it?

almost looks like the orange part is an O ring? A pressure sensor of some sort?

I believe it is a vapor management valve of some sort.
