Leaking fuel tank - again

[Waiex191]

Perhaps someone melted the screen when they etched the tank in prep for the Kreem?
Gas wouldn't do it...it had to be something nasty.

That's the odd thing.  I did the etch/Kreem back in '91 or so.  I've had the petcock out when I brought the bike back to life a few years ago.  So - there has been nothing in that tank but gas.  Initially I was using the ethanol contaminated gas, but after having to redo the carbs again I decided never again.  I'll pay the extra $2/gallon.

It's a mystery.
