One would have to use something more substantial than a simple plug to cap the line used for fueling though !
A fill line could be ran directly to the tank.
I don't think so. u still want to fill at the UAT to make sure that it is "toppoed off" before each flight. Filling at the UAT is essential to remove any air introduced on previous flights thru aggressive manuvering or any other cause.
