I made a discovery about the ESB gauntlet hose connection. I don't have any screen shots to prove it at the moment, or any pictures or diagrams, but I will make them soon. Please don't criticize me if this has been discovered before, because I have searched for it and found nothing.
But I think that the ESB hose on the right gauntlet has a little inner black hose inside the transparent sink hose, and the little black hose goes inside the gauntlet, (like where the dowel would go on the ROTJ version). And the sink hose simply "hangs off" of it. I know this discription is very sketchy, but I will provide a screen shot when I get home. But, I have a picture of my hose right now, so I'll show you what I mean.
If you want to see the seen right now, put in your Empire Strikes Back DVD, fast forward to the part where the Falcon deatatches from the star destroyer and floats away with the garbage, and freeze to the VERY FIRST frame that it shows Boba in the cockpit. It is very important that you freeze to the VERY FIRST FRAME you see Boba in the cockpit. Look at his right arm, and zoom into the part where the hose connects with his gauntlet. I'll put pics up soon, but you do this for now lol.
This photo shows me inserting the black hose in to the sink hose
This photo just shows what it looks like done, (I will get some screen shots to back me up)
