I am just wanting to know what these 3 things are and for what.

First is a plug with a block off it is in front of the motor i believe it just comes like that factory for what ever it is for.




Second is a vent looking deal that is at towards the bottom of the first wall on driver side. My concern with this is if it just hangs there are suppose to go into something are what not. Seem when i follow it to the end it goes to the transmission to metal looking tubes.



Third just seem like something should be plugged into it. Its right on top of the fuel filter not sure what its for and if needs a plug in.



Much help appreciated.
