my fuel tank on my scrambler has a small fuel leak on the bottom where the fuel lines come out of the tank. what can i use to fix the leak?

 

If you mean around the fuel petcock,you should be able to drain the tank,remove the petcock assembly and replace the gasket around it. If there is an actual hole,it will need to be repaired, there are several chemical tank repairs out there,just don't use Kreme, the coating eventually comes loose,and plugs up your carb or filter.
