Gas leak

No there is not. Either get it repaired, but good luck in finding someone to do it, but there are some who will, otherwise the gas tank needs to be replaced.

I would absolutely just replace it, not worth the hassle or expense trying to repair it. Most leaks are from rust and you do not want a rusty gunked up tank unless you enjoy replacing fuel filters and pumps.

If it is a pin hole rub a bar of soap into the leak.
