307 gas gauge

Hello friends, despite the fact that I have not bought petrol for my 307 peugeot vehicle, there is no progress in the indicator.

The float is attached to the ramp and will come back to its normal level when you stop or add some more.

Thank you, I bought gasoline and it was flat, like now.

If you take down at least 10-15 liters of gasoline at a time, the float does not feel the difference. it doesn't send signals because I bought gasoline in the brain, so the needle doesn't play. If you buy at least 10 lt, the difference is noticeable, but the pointer moves accordingly. some friends are leaving the ramp, maybe a solution.
