Problem:
I noticed this evening at the service station that gas was leaking out just in front of my rear passenger tire while I was filling up. I would say up to a pint flowed out per the 19 gallons I pumped.

Note:
My service engine light threw P0456 (small EVAP leak) exactly two weeks ago. I filled with gas that morning, and didn't notice anything. I cleared it 200 miles later the next day, replaced the gas cap with a new one, and no codes have appeared since (I have driven it another 200 miles).

Before I tear into it and report back, any thoughts from the forum are appreciated.
