fuel tank, pump and driver question

[pnypwr289]

I bought a turbo setup for my 03 mach, it didnt come with a fuel system upgrade, it was a used setup. I found on cl a termi dual pump hanger assy no sender for the level that was brand new. question is do I need to upgrade to the cobra tank? will my fpdm drive both pumps or do I need one from a cobra? seeing as im not looking for huge power the engines stock im thinking 450 hp max, should I mothball the termi pump and go with a svt focus pump, and not mess with life in my stock mach tank? first gas turbo vehicle so Ill be asking some questions, ill try not to be a pain in the rear...thanks in advance
