1. A hydraulic fracturing system, comprising:
an electric pump having an inlet to receive an inlet fluid supply;
a suction stabilizer/dampener fluidly coupled to a suction end of the pump;
a compressed gas supply;
a first flow path extending between at least the compressed gas supply and the suction stabilizer/dampener;
one or more pressure regulation devices associated with the first flow path; and
a low pressure fluid supply upstream of the suction stabilizer/dampener, wherein a second flow path extends between the low pressure fluid supply and the suction stabilizer/dampener.
