what are these???

[jasonroman]

changed valve cover gaskets yesterday. and while i was hosing down the engine bay. i was wondering what some of these things were??

i noticed a line that goes into carb had a little hole in it on the bottom side. never touched it before so i didnt notice. but that was one of the first things i touched. and when i touched it, i felt water, or so i thought. pulled it off carb and noticed it was swollen and gas was leaking thru.

i traced the line and it went into a round canester looking thing on driver side. below the lights. dont know what it is.

so i looked around and took a couple pics of things i was unsure about.
obviously im no mechanic. and lack much knowledge.

thanks for any help.
