Well I have taken the UAT out of my Elan and just use the Orbit Clunk in the main tank, after four flights I have not had a flame out or even a hiccup, I will still keep an wary eye on the pipework just in case, and I also ensure that the feed to the pump is full before I start the turbine and there is no existing air in the fuel lines.

I understand what you are saying about the surface area, but as my fuel is filtered four times prior to getting into the tank I think I have that one covered.
