SF114PXSW0, Is the part I'm looking for the VENTURI TUBE?
Answer Jones, No, The Venturi Tube is not the part you're looking for. Based on your description, the flexible gas supply line attaches to the regulator  which is also attached to the safety valve 98014893. Also attached to the regulator is the gas tube 98007429 This tube is routed up the back of the range and turns under the cooktop and attaches to the cooktop manifold pipe 98013574. This gas tube supplies the gas to the cooktop burners.
