I have a standard guage and the gauges that are built into the panel. There is also a 3 position rocker switch that I assume switches between the tanks for the standard guage. On the standard guage I can get a reading with the switch in the up position. When I put it in the down position I dont get a reading. I assume the middle position is off.On the panel I get innacurate readings on both. The right tank doesnt even work. I am assuming that the tank that reads on the panel is the same tank I can get to work on the rocker switch/standard guage.So………..Do you guys think I have a bad sending unit? If so, what model sending unit do I order for a 98 Pantera Classic?Thanks in advance,Joey Deans
