Are you talking about the Air Conditioning evaporator, If so vibration could cause it to brake, strange you can is running rough if that is the hose you are talking about. If not post a photo if you can...

It may be due to over filling the gas tank, your suppose to stop at the first click on the nozzle, it may be that the Vapor Canister is plugged. There is a carbon filter inside it. The Vapor canister would have to be replaced. Your check engine light must have come on, Go and have the care scanned for codes, that should give you a clue on what would need replacing.
