My Terminator is not currently set up, but I like the idea of a second surge tank made of stiff material like a capped PVC tube and placed close to the tonearm. I suspect the underlying issue is that a long, soft silicone hose modulates in sync with the pump. It’s likely better to have a short length of hose near the arm, or a stiffer hose material such as automotive hose inside steel braid.
To get an idea of the level of bearing turbulence, place the stylus on a stationary record with the pump running and listen to the speakers with preamp volume turned high.
BTW it’s a great arm. I modified it extensively with a lightweight carbon fiber slider formed over a foam core, and various custom wands and detachable headshells. However, some vintage MM/MI cartridges had tracking issues with it and were better served with an SME 3012R or Kuzma 4P. But the TFT’s general performance is up in that league.
