Here is an older style cap. There is no direct route for the fuel to escape thru this cap because the vent goes from the center hole to a space above the gasket which is open to atmosphere but under the cap shell. The solid top keeps the fuel at least contained so if it does gush out it is confined by the cap and directed down the outside of the fill pipe.

My 56 cap is the locking type so not a fair comparison to photograph but it too appears to vent thru a small hole in the middle and also into a space above the gasket. Except for the key hole that cap is solid on top too.

Out of curiosity, what does the top of your cap look like and where does it vent? If the outer hole is thru the top and that is where it is getting out to hit the door is there any way to make a baffle out of thin sheet metal so it would protect the inside hole from any direct splash or surge of fuel. Possibly a thin plate attached with small sheet metal screws that laid over the hole yet bent up enough air could still flow in from the sides.
