gas tank

[Grams]

When I try to fill my gas tank there is a leak under the rig. Where and what is going on?

There are so many possibilities to choose from…

But they all boil down to two general categories:
1 - A hole in your fuel system where there's not supposed to be a hole; or
2 - You've somehow put fuel where fuel is not supposed to be.

Without more details, it's all just guesswork. If you want help troubleshooting, a description will help. Pictures will help more.
