Of those 2 tabs on the fuse panel, only the top one is for the fuel gauge. The one below it is a power receptacle connected to the glove box / spot lamp fuse.

And that top tab is wired to the sending unit side of the gauge ... it's not a power feed to the gauge. Although, I believe it is normal to see some voltage there with the key on due to it feeding through the coils in the gauge.

Edit: looks like pjmoreland beat me to it ... and gave you the voltage to look for at that terminal.
