Good morning, sir,
The fuel gauge of the vehicle will not exceed half even though the fuel tank is full of fuel but the fuel warning light will display when the fuel in the tank is low. The fuel pump assembly had been replaced, thinking that it was the cause but the problem persists. Could there be a test to be carried out to confirm the cause before the combination meter is assumed to be faulty? Could there be a circuit diagram if possible?

The two wires for the sender go directly into the cluster.

Here is a guide to help you test the wiring and the cluster and fuel level sensor wiring diagrams below.

Check out the images (below). Please let us know how it goes.

Good morning, sir,
The instrument cluster that I could get for the vehicle is a little different, I don't know if it will affect the performance of the car. The one that came with the vehicle is calibrated in Km/hr while the one available is in MPH.
Does it mean?
