The pilot stated he did not refuel or visually verify fuel quantity prior to departing Kansas City. The flight to St. Louis was on the left tank. As the aircraft approached the Columbia, MO VOR at an altitude of 3000 ft MSL, the engine failed. The pilot stated he established a glide, changed the fuel selector to the right tank, fuselage tank, left tank, then right tank. During this time he was required to hold the electric fuel pump to the ON position. This switch is spring loaded to the OFF position. He was unable to restart the engine and selected a golf course for landing. He turned during his approach to avoid golfers on the fairway and crashed on a paved street. The left and fuselage tanks were empty. The right tank contained about 4-5 inches of fuel. The left fuel tank quantity sending unit was found erratic, producing an infinite then zero resistance through its travel from full to empty.
