Surge tank should be build so that its big enough if feeding pump suck air on hard acc, braking or cornering. Surgetank is connected so that if it will get full, it will flow back to main tank.
Or drag style front surgetank, let the G do the work.
Are you planing to run with carb or EFI, if EFI then you can control you pump with your ecu.
I build'd a twin screw blown 572Hemi with custom fuel tank, trap baffles and 3 Bosch 044 pumps and they are controled by Motec so that first only one running but on boost all are on. After one summer, no problems.
