You can always invest in a 99-04 fuel tank and bolt in the Fore Fuel Hat (2/3 pump 255 capibilities)..
Yeah, there's really no room in our tanks for that setup. Getting one from a new edge shouldn't be too hard.. Stacy correct me if I'm wrong but IIRC Fore makes a hat that is compatible with return lines so you wouldn't have to install a Fuel Pump Driver Module, you'd simply have to wire the pumps in and get pumps that are built to run at full cycle constantly like ours are, the newer pumps are not designed to run full voltage all the time, hence the driver modules.
What kind of HP are you running that you need to go that far? A good ol' Walbro 255 will get you to the limit of the stock fuel lines (usually in the 500's somewhere depending on your setup), and if you surpass that you can simply replace the tank unit with a drop-in pickup and go to a larger pump such as an A1000.
