Not sure how you can do that as both the pressure and return line are "T" together and go to each tank.

Yes but not all of the ones autozone sells are good ones. Some are even missing the shuttle valve altogether. I guess they would work OK if you only had one tank.
Example of one brand that autozone sells.
