cool car. iv seen it on here before and assumed it was an aussie ride coz of the aussie(?) throttle body setup. i really like your detailing and rims. some of the stuff iv done is based on what i seen on your car. awesome work.
as stated above, some new cars run a returnless fuel system (i think maybe new commodores do, among others) and fuel pressure is controlled by a variable speed fuel pump. a link wont do this, but you could possibly setup your own setup if you had an electronic controller that either ran the pump at some voltage relative to engine speed, or that controlled it relative to the target fuel pressure. an easier setup would be to run a fuel pump off the motor, like some drag cars do.
i am definitely not an expert in this area so take my suggestions with a grain of salt. personally id just run a return line and be done with it. saves alot of hassle.
another option is to have a surge tank in or near the engine bay, fed by the primary fuel pump, then you have a very short feed line from that to the engine, and consequently also a very short return line to the surge tank. all you'd need is a cutout switch to the primary pump when the tank is full so it doesnt try to pump more fuel to the full surge tank. they had a setup similar to this on 'banzai' crx off the high octane dvds.
by the way, hows the car looking now? almost done? where are you based?
