Gas gauge

Friends, accident-free driving. My vehicle was 2004 307 1.6 and I had a tube and it was about 300 km. There is only one problem like this, although the vehicle spends from the tube, the gas gauge level decreases but it does not spend from the gas. Has anyone had such a problem?

I read a lot about this, my car did not live with gasoline, but I guess it was like working on gasoline, so the brain dropped the needle in that way, I had read it in the forum as a solution, by connecting an apparatus to a half tank or lpg.

burak, as our friend said, just like my 206, there should be no gas under the half tank so that the vehicle is resetting at certain intervals, otherwise you will have to install a separate appartment around 150 TL

Brc brand lpg device is also attached. this problem is getting better. the gas gauge returns to normal every time you switch the ignition off and on. I do not know if there is this system in other brands lpg.
