Inside fuel fill???

[CK5]

Wouldn't you smell gas fumes with an inside fill like this?

More than likely

 

[Bent77]

Vented outside and a good seal, not too bad likely

SOB to deal with every time you fill up though unless no gate or top

That would suck unless you are the one person in the world that never ever spills a drop.
