Gasoline Vapor Pressure Range
Minimum Lowest Grade Gasolines 4.5
Normal Minimum 6.5
Warmer Climate Range 7.1 - 7.4
Cooler Climate Range 8.0 - 8.3
Maximum 15.0

Gasoline vapor can be ignited only when its concentration in air is between 1.4 and 7.6 percent by volume. At lower concentrations there is too little vapor for ignition and at higher concentrations there is too little air (oxygen) for ignition.

the vapor pressure of gasoline varies depending on seasonal temperature and geographic location (Summer vs Winter and eqquator vs. arctic) ranging normally between 7 to 11 psi
The flammability range of gasoline is usually reported between 1.6 and 7%

The vapor pressure and explosive limits of gasoline change depending on the octane rating of the gasoline. Gasoline with an octane rating up to 100 have these following numbers.  The vapor pressure that is equal to atmospheric pressure(boiling point)is about 122-158*F.  The lower explosive limit is 1.4% and the upper explosive limit 7.6%.
