Emission line connectors?
 

96 850 GLT. Twice in the past week I've got the P0455 code and both times I've located the problem behind the passenger rear tire. One behind the (charcoal canister) ? and one in front that looks like it goes back to the fuel tank. I rubber taped them temporally which cleared the codes each time but I know this wont last. The problem is I cant find the part number or the description of the connectors. They both have different diameter holes on each end and one is long than the other. Can anyone with experience on the P0455 location of these connectors help? Thanks.

Are they close enough in size that a bulk hose will fit both ends and maybe be a bit tight on the other?
