I feel kind of dump asking this question.

I have a Wayne 615 visible gas pump. The measurement numbers inside the glass cylinder seem backwards. They start at 0 (gallons) on the top and then progress downward to 10 (see pic). Can someone enlighten me. It appears to me they should go the other way ( 0 on bottom and 10 on top). Would you not pump the gas into the cylinder and it would fill from bottom to top (if gravity is in play) showing how much gas you have...then release the gas into the vehicle flowing down?

I know there must be a simple explanation but for the life of me I cannot figure it out. Again...please enlighten me in my ignorance!

Thanks in advance!
