You should (as you say) be able to create a new (ignition switched) 12V supply to the sender and then to earth. With the new voltmeter/gauge (or whatever you decide) sitting between the supply and the sender. Something like this...
+12V -----> gauge -----> sender -----> earth
Good luck! Keep us posted...

I dont get it
What I do get is potentiometer with 3 wires. You supply voltage to one, one is ground and rest is altered voltage.
I got green and black wire. I assume black wire is ground, not sure but almost. (theres red and black wire, if i unplug those bike wont run long, both blacks are same) (GR, BL, RD)
I have ignition switched 12v +. (IS12)
I have hand voltmeter with 2 (red and black) connections. (V+, V-)
What to connect where?
IS12 -> V+ ? (it will measure 12V, we need to run it thru potentiometer first?)
IS12 -> GR ? (if BL is ground, i dont get how i will measure anything with coltmeter here either)
