Using Ohm's Law, if the resistance of the gauge is 100 ohms, at 6 volts, the current flowing through the circuit would be 6 divided by 100, which is 0.06 amp. (six hundredths) In a 12-volt truck, it would be just 0.12 amps.
This is just a wild guess as to the resistance rating of the gauge, but you can see how small a current is present. And these guestimates don't include the resistance of the sender, which would lower the current even more.
