I believe the gauge would show empty at empty in this arrangement since the sender would be at 0 Ohms, which would effectively bypass the 45-Ohm resistor (two parallel resistors of 45 Ohms and 0 Ohms come out to a total of 0 Ohms). The gauge will generally read a higher level than is actually in the tank in a non-linear fashion.
