LS 1 fuel return line leak

[cutlassmann]

Need help went to the gas station today to get gas and feel my car up till the gas start coming out so I put my gas cap back on drove them when I stop at the store I notice starting dripping from under the gas tank I look and it was coming from the return line could it be because I over fill it? It's a LS1 motor with a tanks inc EFI gas tank never had this to happen thanks if you gas can give me any info.

The return line is the same type of fitting as the feed (1/4npt) and my guess is you have AN adapters?
It's unlikely to leak there especially because the fuel returns to the same fitting...?
