Default Which C6 Z06 Fuel pump module for 03' C5??

had my 03' C5 with FFS fuel system on the dyno on Monday and its dropping fuel pressure under WOT.
It has been recommended that I just use an OE C6 Z06 pump/module assembly. Car should make around 440 RWHP.
Can anyone please tell me what part number I should order? Bought car used with 113k on it with a hurt motor so I'm not sure if its a pump or regulator issue... either way I want to replace the whole thing now that the tank is out and it was a PITA to remove the tank!

Thanks!

for future reference i think it's because 2006 Z06 used the 05-06 fuel sender, which seems to be almost 2x the price of the 07+ sender which I've read work opposite each other.
