[Spits] Gas guage

I bet something IS wrong inside the gas tank.  Both
gauges are powered by the same voltage regulator.

I believe you can disconnect the sender unit and
replace it with a fixed resistance that should produce
a particular gauge reading, but I don't know that that
resistance is :-(

But I bet there is a 90% chance you need a new sender
anyway.  One other possibility is that the electrical
part is OK, but the float is flooded and not floating
properly.  You can get a new float cheaper than an
entire sender.

Either way, you have to remove the old sender, so
start driving around until the tank is mostly empty...
