This has been going on for a while and I know it isn't exactly a good thing.
After being in the rain or washing I'll find water to be sitting in the space between the rubber gasket under the gas door and the little spring loaded door. Why is rain getting in here? I figured that the little hole underneath on the left is supposed to drain water before it gets down there. I had the tank off earlier while diagnosing my driving lights and I shot some brake cleaner down that hole and it's clear.
There a way to fix this?
