Thinking more about this, it seems that the vent routed to the top of the fill tube (rather than the baseplate), would have the advantage of definitely routing any overflow (thru the vent line) during filling back into the tank. With the vent on the baseplate as I've drawn, it could run elsewhere and I'm sure the filler cap assembly is not hermetically sealed to the baseplate. Of course, placing the vent on the fill tube is not as easy as on the baseplate, if a bulkhead-type fitting is being used.

Cheers,
-Neil.
