So now the question becomes can a 90/0 gauge work?

This should would work, if 90/0 corresponds to empty/full. Needle might be a little off the marks, but not likely enough to matter. Keep in mind the stock wiring will add a couple of ohms series resistance to the circuit, so you're pretty close to the stock figures.
