    David Rizzo: Fill you tank all the way. In other words you don't need to stop and go, and stop and go because each time you do that you are creating turbulence which creates more fumes. Again, you are paying for liquid gas, you don't want those fumes going out and wasting it. So take you time, start it and walk away from the pump and one good reason not to sit there and play with the pump is those fumes are highly carcinogenic. The benzine and gasoline has been attributed to acute Myelogenous Leukemia. So just put the latch on low, walk away, take a break and then come back when it's completely full. You can remove the nozzle. You have got plenty of gas and no problems.
