Call thunder racing. They have a racetrinox setup for the late 03-04 cars. You have to send them your fuel bucket and they modify a new pump to fit it...That should be good to 600rwhp, more than that and you need to call ECS, they have a system good for 850rwhp...

You can also, talk to Racetronics. Although they dont make a pump, they have some sort of new harness that is supposed to increase the volume.
Other than what I have told you, your really out of options..

BTW, "I think" that ECS has done something with a system as well. But I'm not sure.

forgive the ignorance, but what's different about the '03-04 cars? Pumps are available for earlier models, but not later.
if it's as simple as modifying the new bucket to fit a Walbro pump, I'd think a DIY guy could handle it. No?

You might be able to do it yourself, I don't know. I've never seen a pic of the newer bucket, just a line drawing. I do know the the newer FFS fuel system has the fuel filter and pressure regulator built into the bucket so that might make it difficult unless you have done it before. Stupid GM

You Do Not want to drop the tank
Late 03 & 04 have fuel pumps that go in from the top of the tank. Pulling a tank out is a major job, I have been there. First you drop your exhaust system, Second you drop the complete suspension and transaxle, now you can start to fight with getting the tank out, no fun.
I recommend you call ECS they have a nice work around that lets you put in a parallel external pump. It is still not an easy solution, but far better than pulling a tank for a larger single pump that might not even be adequate if you start going 700+rwhp, you will need a return system.
For just a little more fuel a boost-a-pump works up to about 550/600hp with a supercharger. I would talk ECS, I would consider them the experts when it come to this. You do not want to pull the tank.

Fuel System
I bought ECS Fuel System and its on the way.......Its only $1800.00 
Not bad when you have over 25,000.00 on the Car right.
Chris has a similar set up on his car and it works very well
