Fuel gauge on 1985 Chevy Silverado maxed out?

Question type: Maintenance & Repair

So I have a 1985 Chevy Silverado. It has two
gas tanks but the only one that is used has
its own fuel pump and the diverter has been
removed. So it is been set up like there's
only one gas tank. However, I accidentally
bumped the switch today and it acted like it
switch tanks and maxed out the fuel gauge.
The truck still runs and no fuel has been
diverted but it won't let me select my other
tank to see the fuel level. How do I correct

As the switching valve has been removed the only other possibility is the switch itself is also bad, it won't switch the gauge back to the correct tank. On a GM when a gauge looses connection with the sender it swings way past full gauge swing, I have even seen these swing all the way around.

Look for a disconnected hot (+) wire to the gauge. HTH. -Jim
