It's been a balmy 60-some degrees here today, and before I got the truck, it was stored indoors at about the same temp. No tailpipes close to the tank, either - they're on the to-do list for next week.

When I was a teenager, I pumped one heck of a lot of gas, and remember this would sometimes happen with the old style gas tanks and caps, but being young and dumb, never bothered to ask "why"...
