it's because the clunk is too restrictive. ditch it and add a UAT.
Listen to the gentleman from the south.
Felt clunks are good for smoke pump header tanks.
Out of many, many flights I've only ever had one UAT (that's less than 99.9%) ever give me a strange leak.
And yes, if you have a flame out and you get your jet back in one piece, kiss it when it gets back to you.
Even the lightest jet, well maybe not a foamie one with that 1/2N size turbine, will benefit from the UAT. Maybe in that foamie one, the only tank I'd run would be,
just a UAT.
I'm just a poor little north american who needs to minimize his risk to have fun flying.
