Autometer gauge test

It's time to test if my calculations are correct. I have fixed the autometer gauge in order to have a proper setup and to be able to test everything properly.
The picture shows the gauge position on nearly empty and the LED is on. This indicates that the petrol is going to run out very shortly....... I have the mechanical reserve anyway. The switch allows me to disconnect it as I am not connected to the after contact wire yet.

This view shows the 130 Ohms resistor at the back of the gauge.
The PCB will light the LED when the petrol is nearly empty.

Here we can see everything connected.

I need to empty the tank and then fill up to make sure that the needle goes up to the full position and that the LED switches off.
