If the gas gauge is mis-behaving it can effect the temperature gauge and oil gauge. The gas gauge limits the voltage to the oil gauge, temperature gauge and gas gauge itself by reducing the voltage to 5 volts from 12 volts. If the limiter part of the gas gauge is messed up then the gas gauge, oil gauge and temperature gauge will not work. If you find you have no 5 volts going to the oil gauge and temperature gauge then you will need to find what is killing the 5 volts by disconnecting the oil and temp 5 volt input to the gauges and then see if the gas gauge will have 5 volts at the 5 volt feed terminal. Maybe the oil or temperature is killing the 5 volts from the gas gauge.
