Gas pouring out of charcoal canister?

[qu1cks1lver56]

So I sold my 86 to a guy today, and he calls me and says there's a bunch of gas pouring out of the charcoal canister.

I drove this thing everyday for 2 years, and my dad drove it for a few years before I drove it, and this never happened. When we put the new engine in, we didn't hook up any of the lines that went down to the canister, and as far as I knew, the only thing still hooked up to it was the line that came from the fuel tanks.

Any ideas what would cause this? I do know the passenger side tank is full of gas and half a tank in the other gas, also.
