Try filling your tank with a different type of fill tube or find yourself a bottle with a long tip to guide or get further into the tank .A lot of these tank fill openings twist open and there is metal blocking the hole or the juice will run outside of where it needs to be. Their are no o-rings on the fill holes .Just space that the juice has to run over and thru to get into the tank allowing the juice to run outside the tank an into the air holes .Aspire Nautilus is one I am referring too among many others.
