Re: Second gas tank to crack and leak
I use old thick rubber handgrips slit and slipped over frame tube. Use a three or four inch chunk under each mount and don't tighten it down gorilla tight. The tank can still move if pushed hard. Just draw it down snug and don't flatten the rubber completely.
A layer of good double sided tape under the grips and the tank will help keep it secure even better.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
