I always drive into filling stations. Since gas fumes are heavier then air they stay closer to the ground. This way if the fumes are heavy enough to ignite my alternator cooling fan will draw the fumes thru the alternator and cool the sparking off that is going on inside or ignite. If it doesn’t ignite the chances of my frig igniting it is zilch as it has no fan to draw air thru it to cool it and is considerably higher then the alternator.
My alternator has continuous sparking inside a metal housing under a metal hood while my fridge has a small flame inside a metal shroud under a plastic hood with no fan drawing fumes thru the metal shroud. When I see folks pushing their vehicles to and from the gas pumps I’ll turn my fridge off.
The alternator is behind the engines cooling fan, you’d need to be nearly parked on top of a puddle of gasoline to reach the stoichiometric mixture, the correct ratio of fuel to air to support combustion.
But hey, ignorance is bliss as long as
this isn’t your RV.
