Patent ID: 7251983

Claim:
A device for drawing fuel out of an underground storage tank and delivering the fuel to a fuel dispenser in a service station environment, comprising: a submersible turbine pump, comprising: an electronics; and a boom inside the underground storage tank that is coupled to a turbine housing containing a turbine; said electronics electrically coupled to said turbine to cause said turbine to rotate to generate a pressure in said boom to draw fuel from the underground storage tank; and a submersible turbine pump housing that contains said electronics, wherein the submersible turbine pump housing comprises: an input orifice fluidly coupled to said boom; and an output orifice that is adapted to couple to a double-walled fuel pipe having an inner annular space and an outer annular space wherein said inner annular space is fluidly coupled to said input orifice and wherein the inner annular space and the outer annular space are run into the inside of said submersible turbine pump housing when the double-walled fuel pipe is coupled to the output orifice.
