LPG Sequential System

I have Atiker in-line system LPG in my vehicle. While working, I was going to get information about the more or less of the gas spent on gasoline-LPG. I bought 50 TL gasoline about 10 days ago, it was slightly above the first bar, do you think it's normal in the middle of the bottom with the first stick we looked at today? I explained to my knowledge, sorry

A situation encountered in most of the french vehicles, teacher. Our gas gauge falls according to the mileage of the vehicle. If you keep it above the quarter warehouse, its resets and hands come to the place where it should be. Also, if you use it continuously in the quarter tank, it will cause the gas pump to fail in a short time. There is no problem
