Big single pumps get very hot when supplying 900hp worth of fuel to an engine needing only 50hp to drive down the road. Heat kills motors. The voltage stepper slows the pump down to allow it to live. Why do you think most / all factory fuel pumps only manage ~500hp by themselves? Porsche used twin pumps probably because the technology was not around for high power singles, or maybe because they knew a big single in daily use will fail. The small amout of ethanol in your fuel can be combatted by using a bit of marvel mystery oil at every other fill-up to help lubricate all the moving parts.
