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.
May I never boast except in the cross of our Lord Jesus Christ,
through which the world has been crucified to me, and I to the world.
