Got mine all butchered-up; mounted a filler neck in there, but I think I’m going to re-do it.
Still not sure how I’m going to hinge-it.

I was thinking about skipping the hinge and just make it removable, mounted with magnets and a cable tether, so I don’t lose it. It doesn’t really need to have a hinge; you could just pull it off and let it hang while you’re filling up.
