1) Put your toon's vision in First Person camera mode. Note: there are five camera modes in EQ, which you chose by pressing F9 consecutively (assuming you have not changed the default key assignments). You know you are in First Person mode if you can zoom in and out using the mouse scroll wheel. The other modes either use INSERT/DELETE or don't zoom at all.
2) Zoom all the way forward, i.e. you can't see your head.
3) Walk into the tube. Note: the tubes use swimming as the movement mode, and each tube has only one entrance at the top and one entrance at the bottom. Those openings are not shown by the graphics but they are there. They will always be in front of the ramp that you use to walk onto the tube platform.
4) Move forward and up using your fwd key mouse. When you get stopped by a ledge, just do a slight swipe to the left or right (I always swipe right) as if you were using Tinder (heh). If you do this enough times, your toon will swim in a sorta tight circle and clear the ledges.
5) Swim all the way to the top until your toon's head hits the tube's ceiling, then just face towards the ramp exit. Done.
