RE: UAT really needed??
I also want to give my 2 cents to this.
So I fly Jets now since 6 years. I have my F-22 with an AMT Pegasus and two tanks connected by an "Y" Festo Connector plus my Phantom with two JetCat P-120 and two 2,8 l Kevlar tanks not connected to each other.
Non of my planes have an "UAT" or something similar. I just use a Kavan "felt klunk" which guarantees that the Turbine gets fuel until the last drop is soaked out!
So for those who believe that the UAT is fine, OK but I think its just to silence one's conscience. I think its more important to have an accurate installation and never use resoluble
connectors on the pumps suck side.
Here in Germany also its hard to get the UAT.
