How does the Radium tank work, is there a pump in it, after it? or does it just fill up after the intake pumps and retain the pressure?

There is a pump (or two) in the surge tank. The Pump in the main fuel tank feeds the surge tank filling it with fuel. Then the pump(s) in the surge tank feed the fuel rails. Fuel from the rails returns to the surge tank ensuring the level inside the tank never drops. Excess fuel in the surge tank returns to the main fuel tank. This allows you to run your fuel level down to 1.5 liters (the volume of the surge tank) without any fuel starvation issues.
