You can also hook the gage up to a fully charged battery on your workbench and adjust the potentiometer on the gage to read where you want the needle to read. I chose slightly above half at 13.5 volts with gage positioned as it will sit in the dash because of gravity pulling on the needle. I actually cut my needle off leaving a small stub, and super glued on the original needle from the ammeter so it all matches, then made the pot adjustment.
Also if you use a plastic or rubber insulator for your hot lead, run that straight to the 12v feed at the fuel gage, and run the volt gage ground wire washered up right to the gage housing. That is a ground anyways. In my pic, i eventually eliminated the black ground wire as i grounded the gage to the gage housing. You can see the red wire hooking up at the 12v in at the fuel gage.
The rest of the gages are 6 volt. Using a vibrating points reg in the fuel gage. I removed mine, and built a soild state 5.5v regulator thats externally mounted
