Bob,
If you vent is completely internal does it get any of the forward airflow?
A vent facing sideways or in an area which opens to the airflow side will
get slightly negative pressure. It probably doesn't make much difference
in your case since any fuel sucked up from the tank will be stopped by the
anti-siphon bottle.
