There is no way a clunk will follow the fuel in a 4oz header. It would be best to mount a fixed pick up in the 3 dimentional center of the tank, even this way i believe you can get air if the tank goes 1/2 empty. With a UAT the perforated bladder type pick up it would work even if 1/2 the fuel is gone and still not draw air.

Got it
No more questions about UAT, at least from my point o f view.
Mine is installed exactly as Andy said in post No. 2
