Claim 1 reads:
A fuel delivery system for an automotive
vehicle which comprises:
(a) a main fuel tank in said vehicle,
(b) a closed reservoir in said main fuel
tank, an electric pump drive in said reservoir,
(c) a first rotary pump in said reservoir
having a plurality of first vanes, a first inlet
communicating with said first vanes for drawing
fuel from said main tank and a first outlet
communicating with said first vanes for
delivering fuel into said reservoir through said
first outlet,
(d) a second rotary pump in said reservoir
having a plurality of second vanes, a second
inlet independent of said first inlet, open to
the interior of said reservoir, and
communicating with said second vanes for drawing
fuel from said reservoir, and a second outlet
communicating with said second vanes to deliver
fuel to an engine,
(e) both said first and second rotary pumps
being simultaneously driven by said electric
pump drive, and
(f) a vent carried by the reservoir for
venting air and fuel vapor from adjacent the top
of the reservoir as fuel rises in said

fuel level adjacent the top of said reservoir to
effectively close said vent to allow pressure to
build up in said reservoir when said pumps are
running.
