Fuel return line?

[red9535]

I'm trying to hook up my fuel pressure regulator, and i'm not sure if there's a fuel return line for me in my car. 95 Mustang, origionally a 3.8 EFI. There's 2 other hoses coming out of the same spot where my fuel line comes from, presumeably one of them is a return line, could someone point me in the right direction?

Thanks
