Wait i think I remember now. Its been almost 2 years so bear with me on this. See the little silver clamp looking thing at the base of the hose there. You will need to take a flat head screwdriver and place it inside that and bend it out some. It is ok to bend it. You will not break it. Then this will release that hose.
