I'm not sold that the brass tube would have much impact one way or the other in that test; even normal fuel tube be it tygon or viton or BVM line is not going to allow the clunk to double over to the front of the tank and stay in the fuel 100% of the time. Also, that video is why we run UATs. And yes, while that extreme scenario might introduce some air into the UAT, most UATs are designed such that you would need a LOT of air to have it reach the engine.
