OK sorry for the delay i was just in one last week to answer your questions in order
NO!AND NO! LOL the tank is the best way to go. if i may i would recommend doing a power wire upgrade to the FPDM (driver module in the driver rear quarter panel) on a 03-04 that fuel system can support up to about 550rwhp with 60# injectors. and about 520rwhp with 42#injectors the wire upgrade will help cary the pumps a little further about 10% more range
Hope it helps sorry i didnt see your post sooner.
