Thank you for your query.
To get Fuel consumption, the parameters would be 2F (Fuel Tank Level Input) and 5E (Fuel Rate) (https://en.wikipedia.org/wiki/OBD-II_PIDs).
But from your provided pictures we see that you can't get them from your vehicle. As an alternative, we can recommend to use GNSS Fuel Counter feature (https://wiki.teltonika-gps.com/view/FMB001_Features_settings#GNSS_Fuel_Counter). All you need to do is set values by your vehicle technical specifications, set GNSS as Speed source on System settings and turn on Fuel Used GPS and Fuel Rate GPS parameters (https://wiki.teltonika-gps.com/view/FMB001_AVL_ID#Permanent_I.2FO_elements).
Also, we see that you are using the old firmware. In this case, we would like to recommend you to update this unit to the newest base version 03.25.15.Rev.01. We would like to inform you that we do not share firmware files / updater and other files in the community forum. To receive firmware files, updater and documentation on devices, please contact your sales manager.
