A liquid will absorb a gas (air) at a rate relative to it's pressure. Henry's law - Wikipedia, the free encyclopedia Atmospheric pressure is 14.7psi or close to it, so your fuel should have a partial pressure of air unless you expose it to some kind of vacuum.
Ideally a liquid can exert a pressure but can't be pressurized so there must be something to press against for your fuel system to have pressure. Most of the time this is the diaphragm in the regulator, but if you have a little air in the system it will be compressed in to a smaller volume, think about 1/4 of it's volume but 4x it's density. Then if doesn't get trapped in the test port, then it is easily squeezed out the injectors.
I can't see them doing anything that isn't already being taken care of.
