You could IF you were draining from a closed air tight container, and IF the line into the genny's tank is extended below the level of the vapor system intake. Would work like a water cooler bottle. 

Nope, once the level inside the "lower tank" drops below the end of the inlet, it allows air UP the hose/connector, and into the upper tank, once equalized, fuel would flow down.. repeat until fuel level in lower tank is again above the inlet point of the hose.

I use a 10 gallon aquarium as a holding tank for the top off water of our reef tank. Water parameters are very strict when dealing with live coral. In the winter our evaporation rate can approach 2 gallons a day. When we need to be gone for a week or longer, I place a extra, full, 5 gallon jug in a holder I made mounted to the top of the 10 gallon tank.. as the top off pump runs as needed, when the level in the 10 gallon drops bellow the opening of the 5 gallon.. bloopbloopbloop.. tops itself off. During the summer, when the evaporation rate drops dramatically, it may take 3 weeks or longer between needing to refill..

Now, I don't think this is how this system works.. but it is a method a person could try..

I would try this if you can find a bolt on the block somewhere to bolt to. http://www.amazon.com/Genuine-Briggs-Stratton-808656-Fuel/dp/B002I1AI0Q
It works by engine vibration, my Vanguard 18 HP has one on my Walker mower. I had one go bad and when I replaced it, cranking the engine was enough to get fuel back to the engine.
