If you have a truly air tight system, you could pressurize the farthest tank with a small air compressor. It would have to stay up with the pump volume so the pump doesn't create too much vacuum.
Have a hysteresis pressure switch (say close at 30psi and open at 40psi) monitoring the farthest tanks pressure to turn on the compressor when the pressure drops. Again, the farthest tanks tube feeding the next tank would need to draw off the bottom, and so on.
That sounds great in theory but I bet you would be forever chasing leaks in practice.
I like venting the farthest tank to atmosphere and daisy chain the tanks with all the draw tubes feeding off the tanks bottom. The tubes will have to be large enough in diameter to support the pumps flow demand. And you can't have any air leak throughout the system.
