When I fill my car up it goes to full. After driving around the gauge will go down to 1/4 then go back up. It does it at random times. I checked the connections on the sender. All good. I checked all the connections on the gauges and there tight too. I know there is a 12v to 10v relay. Is this the one? It reads 12.2v on one side and 11.8 on the other. Is there anything else I should look for or is prone to happening?
