There are 2 hoses, one for the canister which collects fumes and one which is a over-fill so if you spill it just goes to the street. You can take both hoses and T them together so they'll spill on the street. You don't need that bloody canister, thats just for DOT/EPA regulations.
Getting a new seal for the fuel cap, may help... but I doubt it, you could have another problem which I've encountered before when the rubber over-fill piece gets worn out and cracks. I'd take the cap assembly off and check underneath it. You should have a piece of rubber sticking up from right next to the fill hole. That can crack and eventually break off causing spilled fuel to hang out there, where its not needed.
