In RealDash OBD2 connection settings, there is an option ‘OBD2 Monitor’ which allows you to enter any commands to your vehicle and inspect the responses. This should help you to analyze what data your vehicle is sending.

Regarding fuel level, see this post:

You can purchase an OBD2 extension cable and use USB version of the OBD2 adapter. See recommended adapters here:
