CBR650F Question regarding the fuel gauge

I'm pretty sure it starts at 2L (0.5 gallons)
Just to inject more data, mine started blinking and I put 0.5 L on it to get to gas station. Couldn’t fill more than 10.35 L in the tank! This happened for the third consecutive time. Not really sure if its a faulty sensor... its really annoying

Didn't want to start a new thread and this seemed the most appropriate one to add to. Filled up the tank fully last week for the first time since buying the bike recently, and by 100km it had dropped down to the first bar. Then just now on the way home from work it's started flashing at me after 130km from full, and showing 7L used at an average 5.5L/100km.

So now I have to watch that damn blinking gauge for the next 130km before I'm anywhere near needing to fill up. Zzz... Time to investigate replacing the sender I guess.

On my 2018 CBR650F, it seems to start blinking when I have slightly over a gallon remaining. I've run it up to 3/10s of a gallon counting up, and never been able to add back in more than around 3.3 gallons.
