I'm going to call this a coincidence, these tanks are well known for rusting through on the top. The tank on my 2001 Accord rusted through last year; at first I would catch just a whiff of gasoline smell after a fillup and wondered if there was an EVAP leak; then one day there was a puddle under the front/left side of the tank. When my shop pulled the tank (which requires dropping the entire rear suspension), I could see stamped in depression which had a hole maybe half the size of a dime all the way through the metal.

"....requires dropping the entire rear suspension" that is not a nice thing to have to do.

Honda designers! ARGH!

Wondering when I'll have that problem now.....

It will probably pass if you bring the car in when there is less than a half tank of gas, errr, until it starts throwing codes (which will eventually happen).
