The only car I can name that is fuelled like that is the Trabant, and that thing is old and long out of production. And also crude as all hell, but that's a story for another comment.

I don't know of any car currently where you fill the gas tank from the engine bay.
Maybe this is a natural gas conversion.
EDIT: Yep, illegal conversion.
