Hey everyone. I am currently building my Zam and after a long, arduous start things are starting to come together nicely. I was wondering if there is a definitive source for the hoses that connect to Zam's waist in the front? I recognize that hose, with the wire running through it and all but I just can't jog my memory as to what kind of gadget I've seen it on. I apologize if this is listed somewhere else on the forum. I looked for it but didn't see it anywhere.
