Fueling & Injection - in tank or inline

FI systems = go with either dual intank or sumped inline

nitrous = fuel cell inline and single intank.

is this right? And if so which is the better option for FI system. My cares are in this order

#1 price
#2 supports 700-800hp(for the future)
#3 reliability
#4 easy of troubleshooting
#5 noise

If i were you id move reliability up to #1, Id hate to get stranded somewhere because my fuel pump went out. If you willing to sump the tank and run an inline thats what I would do. It would make for easier acess to the pump if needed.
