Exclamation 05 Expy P0455 Gross EVAP Problem

It seems I have a gross EVAP leak... code P0455. Does anyone have any clues for where to start looking? Are there any usual places for this to happen on a 5.4L?

** Something Fishy**
In looking for said leak under the rear I noticed a hose that was not connected to anything at all. It is right next to the gas fill tube and actually zip tied to it. Seems to me it should be connected somewhere but I do not see a fitting. It goes back to the large black thing that must have something to do with the EVAP and fuel system. This vehicle was wrecked in the rear before I got it.

ANY advice would be greatly appreciated!
