[Solved] Water fill leak - '95 Roadtrek 190 Versatile Dodge

It is a Dodge chassis, but in this year (1995) the gravity fill is in the front passenger side step well inside the door.

I can actually see the tank when I unscrew the fill cap thing, so I can see where I need to undo the hose, just don't know if there's an easy way to get there.

It's basically right behind the front passenger side wheel, but the hose connection is on top, facing toward the rear.
