Their is a transfer pump inside the rear tank that transfers the fuel to the side tank this is possibly the cause of your issues..

I put gas in my car and the gas hand fell to empty and when i turn the car off the gas hand comes up on my 94 caprice

Sounds like you need a new fuel sending unit. It is a big job because the device is located inside the gas tank. You have to drain it, drop the tank, replace unit and reinstall the tank.
