cn90, good call on drilling the hole, it actually may be better to leave that hole open since I think part of the problem is there isn't enough airflow with the "big ass cover" on there and the moist air/salt gets trapped.

If any of you guys are having to drop the cover to fix the brake lines, consider replacing the fuel filter as well just while its open.
