Behind drivers side of the bumper on my 1997 grand Cherokee theirs a black plastic part that has been damaged so it needs replacing but I don’t know what it is, it appears to have three hose’s going to it two of witch seem to be fuel and not shore of the other one. Anyone know what it is???? Thanks for the help

I believe you're referring to a charcoal vapor canister. You should be able to find one doing a Google search.

yup he's right, it's your Evap Canister (Charcoal Canister).
