Kevin,
The Walbro fuel pumps like Tracy sells are closer to
what you want. I am not sure of the weight, but I would guess about a
pound.

I don’t remember if Tracy sells the 391 or the 393, but they
either one would work and they are the same price. They pull about 5-6
amps and will flow enough fuel on battery power alone to feed your engine at
full power. Even at the 44 pounds of pressure you will be running at, not
the 3 pounds of pressure in your example. That low pressure is for carbs…are
you running a carb on the Renesis??

I want to know why electric fuel pumps for
race cars have capacities ranges of 71 - 90 gallons per hr at pressure?
they don't burn anywhere near that, do they? when looking at pumps, those
capacities seemed pretty common. why? weight is a consideration in
race cars as well as airplanes, right? the Holley red pump, 71 gal/hr @ 3
psi weighs 3 lbs and is huge. my renesis could never use half that
capacity, right?
