It has been my belief that the UAT is really NOT needed. I too have used a 2oz header tank with a center pick up in my "for sale Bandit" and never had a flameout or else it would not be here for sale.

I use THREE kero filters in my 5 gallon jug. An Auto filter with a glass body, a paper filter and a FESTO large filter. I keep my kero sealed the best I can and out of the sun or humidity. I take it out of my van if I do not fly for more than a weekend or two. Although I had kero sitting in my garage for three months and I just finished flying with it, no problems. I use Exxon oil in case some one wants to know. Hope this adds to the confusion
