The 2000 M Roadster has a fuel flap on the passenger side. Inside is a fuel aperature and gas cap, below which is a neoprene shroud. In rainy weather, it's not unusual for me to find an inch of standing water in there. It's well below the aperature, so there's no acute gas/water mixing problem. However, it cannot be good to have that water near metal parts and fuel. I considered poking a hole in the bottom to let it drain down. Maybe one is there by design, and it's just plugged up? I don't know if the water is coming in around the filler flap, or if it's coming up fromt the rear wheel well. Ideas?
I will be glad when summer is finally here.
