So this collector means you do not need a surge tank. Is that right?

Probably. The collector is like a box that surrounds the fuel pick up, and has flap type doors - like a road racing
oil pan. Like the
oil pan, it helps to trap fuel around the pick up, so it doesn't go lean. My SA110 has a collector, and I can run the tank almost dry before is sputters in a corner.
A surge tank is another small fuel tank mounted near the fuel rails, in the engine compartment. That tank is fed by a low pressure pump. The surge tank has it's high pressure pump (for EFI) that will feed the fuel rails. I think this system is in very limited use, as I'v never actually seen one.
If you mount the surge tank in the back of the car, all you've done is create an external collector. Not sure there's a lot of value to it, considering the cost, complexity, and weight added.
