I think that has to do with new emissions regulations. With the old fuel system, you run a bunch of fuel up to the engine and some of it gets used (usually very little). The fuel heats up while its in the engine compartment. I think it releases some contaminants when it gets back to the gas tank and those eventually make it out to the environment. So the later fuel system only sends as much fuel as is needed to the engine. So you don't produce any extra pollution by heating/cooling the fuel constantly. I think I read this in SCC a while back...no promises on the accuracy.
