NO. External pump will NOT draw fuel through a failed Ford Internal High Pressure Pump. I spell that out because you can draw fuel through the older low pressure pumps used with carburetors. But if it's a High Pressure, it at least has to be spinning, even if only struggling, to not serve as a shutoff down in the tank.
I'm told most fuel pumps PUSH fuel better than they PULL it. That's part of why they're in-tank, they're close to if not submerged in the fuel. Another part is that liquid fuel won't vapor lock. But Alas, I'm sure COST plays a major part. Expensive to repair doesn't count to the designers. Cheap to build does.
