Its quite simple to replicate the exceed tubeless kit, I prefer this way than having a short length of pole hose trailing out the bottom of the pole. You just need to make a "bung" of some sort that you wedge in the bottom of the first section of pole, even a cork will do. Drill a hole through it and feed the hose through , cut to length, stretch it reasonably tight and and secure a rectus male fitting with an o clip. If using a univalve you can make a hose retainer for where it comes out the gooseneck cut from a section of plastic drainpipe or similar with a hole cut in it.
Someone posted instructions on similar a couple of years or so back, using I think, a jg plactic pipe insert as the "bung" or end stop in the first section of pole.
