Whatever I do I cannot get my autosiphon to hold a seal while siphoning. Everything will start out perfectly fine until about 15-20 seconds into the siphon it starts to suck air in at the seal on the racking cane inside of the siphon tube. I have tried putting keg lube on the seal and several other things but I cannot get this thing to work, I am probably going to give up on this and build a different type of siphon.
