Fuel tanks
I think I know the answer to this but not 100% sure. Assuming I start with a full tank of gas, as the amount drops as I drive my vette, does the volume in both tanks remain balanced, or does one tank (presumably passenger side) empty first before the other one (driver side) starts to empty? My guess is the latter but not absolutely sure.

I was assuming that the pass side would empty because why would the drivers side do work of sending fuel back to a storage tank and waste volume on not flowing to the engine? I am pretty sure the fuel pump in the pass side pumps to the driver side and does not recieve any back, but I could be wrong.

From the 2000 manual:
Fuel Pump
An electric high pressure fuel pump attaches to the fuel sender assembly inside the left fuel tank. The fuel pump pumps fuel to the fuel rail assembly at a specified flow and pressure. Excess fuel from the fuel pressure regulator, a part of the fuel filter, returns to the left fuel tank through the return pipe. The fuel pump delivers a constant flow of fuel to the engine even during low fuel conditions and aggressive vehicle maneuvers. The PCM controls the electric fuel pump operation through a fuel pump relay.
The left tank fuel pump also supplies a small amount of pressurized fuel to the right fuel tank siphon jet pump through the fuel feed rear crossover pipe. The pressurized fuel creates a venturi action inside the siphon jet pump. The venturi action causes the fuel to be drawn out of the right fuel tank. Fuel is then transferred from the right fuel tank to the left fuel tank through the fuel sender fuel feed pipe.
