This is what we´ve talked about ... although we have 92 kg supply tanks capacity (S/N late 600), indication is always 44kg and 40kg...
I found this note in Training manual:
*4 kg can not be displayed, bacause for crash safety the fuel sensors must not contact the fuel cell ceiling
Or this, in RFM, about Supply tanks I and II:
*
values depending on the type of fuel tank
