Does 1998 V70 have charcoal gas canister for evaporation? If yes, where is it located? When I open the back gate, and pull out the floor panel on the right, next to gas tank, I see some lines and a thicker looking one that attaches to small plastic square looking 'thingy' bottom of which goes through hole on the floor to 'something' bellow. This connection is not very tight, I don't know if it is suppose to be. There aren't any things in the area that look like typical cylindrical canister.
