I would agree with you if he were talking about drawing liquid gasoline 
from a pool of fuel but that is not what I read.  Yes, there may be a small 
amount of gasoline fumes present.  If some fumes were drawn into a vacuum 
along with a large quantity of added air it would be almost impossible to 
ignite this fuel mixture using a spark.  Combustion simply does not happen 
when the mixture of fuel and oxygen are outside the combustion limits for 
the components.  The combustion limits are the highest and lowest A/F ratio 
which will sustain combustion at a specific temperature-pressure 
combination.  You see a hint of this when trying to start an engine with a 
fuel mixture which is too lean (too much oxygen for the available fuel, the 
A/F ratio is too high).  If the fuel mixture is too lean then no amount of 
cranking will get that engine to fire.

In short, don't try to "suck up" liquid fuel with your vacuum 
cleaner.  Don't worry about getting a little fuel fumes into it, though.
