I've glued airline tubing inside the utube.... when I am starting the siphon I just suck on the tube until all the air is done. You can do it periodically as well, when a bubble collects in there. After I do it, I cap the end with an adjustable adapter or an air valve. Lemme see if I can get a pic. We may have removed it because the tank is just a LR tank right now.
