I can't find a topic how reset the fuel indicator if happen to disconnect the fuel pump connector without switching off the ignition key. I got this reference from the Workshop Manual pages 72. I appreciate for all input. Thank you.
"Should the fuel pump electrical connection need to be disconnected, it is imperative that the ignition should be switched off. If the ignition is on in any position the fuel gauge will memorise its last needle position prior to power down. Once power is restored the gauge will display the last remembered position regardless of the actual level of fuel in the tank. This will result in incorrect fuel gauge readings if the fuel tank has been drained and not filled worth exactly the same quantity of fuel that was removed."
