Sure it could, but you'd need to upgrade your fuel lines, fuel cooler, and fuel filter to handle 100 PSI, and you'd need another pump to make vacuum for the brake booster and VNT control system.This thread is fun.
Now the question is can a gasser in-tank pump supply enough fuel to omit the tandem pump entirely?
Inquiring minds want to know
It makes more sense to transfer the fuel with cheap low-pressure components, and then bump up the pressure only at the final point where it needs to be higher pressure (in the passages in the head that the injectors feed from).
I can't think of a better way to run the vacuum pump that right where it is on the end of the camshaft, and since that's gotta be there, you might as well make it pump fuel too.
