Air, unlike gasoline, is compressible.  Even quite a lot of air-sucking
only occupies a little space in the lines, and because it has a MUCH
lower viscosity than gasoline, it also flushes through the control
pressure regulator and back into the return line in a flash.  The accumulator
makes up the lost volume very easily.  Not much (if any) gets to the
injectors.
