Well, per Peggy Hall, you want good air flow to prevent anaerobic decay
and thus odors.  The mission of a fuel tank vent is different.  Those
vents will limit airflow at least a little bit.

I used straight delrin through-hulls, mounted high on the hull up near
the bow; I got the idea from the A-30 site and one of the regular
posters here in this list.

It's worked great so far.
