Question:

Im getting ready to install this device and want to know what the two devices are mounted on both ends of the tank do. How do they work?

On either end of the tank from the kit part # SM99627 that you referenced is basically regulators. On the input side it's a valve that opens at 80 psi and above and closes at 70. The other side is a regulator that provides the system the correct amount of air pressure to apply the vehicle brakes until it runs out of air pressure.
