I would advise changing the cheapo plastic Q Disconnects before they fail and you get stranded.
If you want to drain the tank just release the disconnects to seperate the lines. then use a small philps screw driver or other type tool in the center of one of the disconnects, push in to release the spring valve and the fuel will fall out.
One of those hoses is from the fuel pump inside the tank and the other is a fuel return from the fuel rail on the engine to the tank. I don't remember witch one will get the most out of the tank, try them both.
