WiideglideJoe Joe You can get a fuel pump that will support 1000HP IF it has a large supply line. The limit on your fuel pump will be how large the pickup is in the tank?
This was a problem with many 1/4 mile race cars and dual carbs. NOT ENOUGH SUPPLY. 1000ft and the cars are running out of steam. Min size line is 3/8" and this has limits. This system would also be run with a electric pump in the back of the car. You will need and external regulator also. If the return line is run, buy a better regulator with return. This will stop surging in the lines and float jumping in the carb bowls. This doesn't happen alot but have seen motors get gas washed from the diaphams going bad, and the fuel leaks into the motor instead of out on the ground.
IMO electric is a better setup. Toggle switch(hidden or anti thief) relay, fuse holder, and fuel pump with larger lines #8-#10. Do it once and forget it.
