There is a lot to consider when it comes to trying things like this. For a carbureted vehicle a geet apparatus would help vaporize the fuel such that from vacuum more vapor is present and less fluid. Fuel injected engines it won't work as well, injectors and the heat inside the combustion chamber maintain fuel as a vapor. Changing the injector duty cycle is the only option, the O2 sensor will compinsate for a lean burn, so actually both need to be set at a new range.

Then there are the fluid dynamics, the volume of a fluid is effected by its temperature. A fuel at 90' takes up more space than @ 60'. Most modern cars have an evap system that collects vapor as well as the tank is insulated, mostly for crash purpose, but it allows less fuel to be loss threw heat exchange.
