Hey,
We just had a torrential rainstorm. When things dried up I took a spin to get gas. I popped open the fuel filler door to find quite a puddle in the compartment. I soaked it up with some rags I keep in the car for polishing. There seems to be a drain - at least there's some kind of hole beneath the gas cap which I figure must be a drain. Never had this happen before. Maybe it got plugged somehow?
