Man, I HATE people who do this kind of thing. I'm sorry someone did that to you. Luckily, you have a few options to fix the tank without replacing or removing it.
There are expanding plugs made of chemical resistant rubber for exactly this scenario. You may need to make the hole bigger to use one. Make sure it is nitrile rubber or rated for fuel (epdm).
Since it's so small, you can probably use this putty meant to fix holes in fuel tanks. I believe it's epoxy.
Here are two examples I found.

I would definitely leave the hole smaller to begin with.
It's not cheap, but this permatex stuff worked on a buddy's Mazda gas tank.
