If the Aeromotive pump will handle 800WHP boosted I'll eat my shorts. I've seen their pumps in action - they are overrated.
If you want to go in the tank, then the Walbro twin 450 or AEM 380's, if you want to go external, then the Bosch 044's.
It really comes down to how much HP you intend to make and fuel. If you ever plan to run corn, then plan accordingly in terms of pumps and line size.
Mike mentioned it - don't cheap out on the fuel system. It has to be bulletproof if you have any love for your motor(s) at all. 14:1 at 15+ psi happens once - if your lucky.
