I think all your ideas are good, however, I'm not sure if a rigid UAT alone will solve it


However, it is still good to keep the UAT from collapsing. If you suddenly cut the power when the UAT is collapsed, the uat will also suddenly expand, momentarily starving the system, and since you are at idle, it might cause a flame out.

Interesting discussion....

You're 100% correct Jack. That is why I have stated 5 points to look at in the first thread for a proper fuel system setup ( including a 3 lines sentence about fuel restriction ).
The UAT is only one of the 5 points.
However I wanted to start this discussion to point out this specific UAT suction problem which is not very well known among jet modellers and talk about specific fuel system test routines...
