had the same problem a slow drip from around the bolt holes on the fuel pump that I was hoping was just a bad o ring or something small. . Took it back to the dealer and after they took the tank out they found it had a hairline crack around the neck of the inside plastic. So a 1 1/2 weeks later kawi got a new tank to my dealer and no leaks. But here is the thing I had already put about 6-7 hours on it with no leakage at all...
