The mixture cannot burn when it contains more than 7.6% gasoline because it is too rich to burn.The vapor density is the weight of a vapor relative to the weight of air. The vapor density of gasoline is heavier than air and therefore will sink when in air.

Vapour density - Wikipedia, the free encyclopedia
Vapour density is the density of a vapour in relation to that of hydrogen. It may be defined as mass of a certain volume of a substance divided by mass of same volume of hydrogen. vapour density = ma...

Substances with a vapor density greater than one are heavier than air and tend to accumulate in low places. Gasoline has a vapor density of 3 to 4. At normal temperatures, liquid gasoline is producing vapors that can catch fire, and which accumulate in low places.

Chemical vapors and gases can be divided into two groups based upon their vapor density:  chemical vapors and gases which are heavier than air, and chemical vapors and gases which are as light or lighter than air.  Using air as a reference point and assigning it a value of 1 ...

The relative weight of a gas or vapor compared to air, which has an arbitrary value of one. If a gas has a vapor density of less than one it will generally rise in air. If the vapor density is greater than one the gas will generally sink in air.
