ABSTRACT:
A fuel vapor reduction apparatus comprising an inert gas receiver, pressure sensor of the vacant volume of a fuel storage tank, external pressure sensor, a non-permeable expandable member disposed inside the fuel storage tank, and an inert gas regulator that is responsive to a predetermined differential pressure between the pressure of the vacant volume inside the tank and the external fuel storage tank pressure, whereby, the expandable member is able to expandably receive and hold the inert gas to fill the vacant volume and reduce fuel vapor formation.
