??? your rebuilt part arrived today, yes?
but to answer your question-- the jumper wire is the same as running your fuel pump on the highest of the 3 speeds of the fpcu controller all the time. think of it as completing the circuit with battery on the high side of the fuel pump and the low side is open (pump wont turn) until you put in the ground wire, or connect a functioning fpcu. The speeds of the fpcu is essentially a 'fan switch' in the return path, but it auto selects the switch speed based on engine load.
you'll see that the rebuilt fpcu has a monster size ground wire soldered in (it's white, but color doesn't really matter). it's the ground path in the factory fpcu's that opens up and then the pump won't turn since current wont flow.
but, yes, you could drive on high speed all the time, might add extra pressure on pump, filter, hoses, pressure regulator. but it might actually be a good thing for a short while.....still a temporary fix, though.
