i run efi pumps in all my cars they can handle the volume needed at psi and maintain it thru the whole pass

The pump was recently checked by a mate at an aircraft mob. It was in good nick but flowed considerably less than advertised (600hp). That being said it was enough to support 127.98mph at over 3600lbs with a stock pick up location. It's probably time for an upgrade, how do you set your efi pumps up? Do you run return lines, pick the fuel up from the stock location, surge tanks, sumps etc.?
