It is my understanding that the expansion tanks are for expansion of gas va=
por=2C not liquid gasoline.=20

The top of the filler pipe is indeed higher than the tank=2C but the gasoli=
ne shouldn't get right up to the top when filling. The gas pump should stop=
 it well before that=2C and also=2C on later models=2C there is a piece in =
the bottom of the filler pipe where it goes in the tank to prevent this as =
well. It looks like a ping-pong ball inside a small plastic cage.

I know of a guy who has totally removed both of his expansion tanks and he =
says he has experienced not ill effects. I'm not recommending it=2C because=
 I don't know enough about the system to know whether they're necessary=2C =
and it apparently may depend on the ambient temp?=20
