Some advice please:

There is a tiny draining hole inside the fuel cap (on the collar) that is supposed to drain moisture away so it doesn't get into the tank when you open the fuel cap. The thing keeps on blocking up. Someone suggested blasting it with carb cleaner, which I did. And it worked. For a week!

Any suggestions for a more permanent fix?.

Note - my bike sleeps outside and the semi-decent rain we had in the Cape this winter probably doesn't help!
