Michael,
My Dodge Dakota sat with a full tank for a year & a half & it still smelled fresh. Once a week it was run for a short while, to keep the battery up & to keep the fuel pump WHIZZING.
The closed venting system probably helped. I "wonder" if it would help on a Model A, to put plastic wrap on the neck, then put the cap on, to help keep moisture out???
