Missouri Revised Statutes Title XXVI. Trade and Commerce § 414.072. Measuring devices, certain fuels, inspection, when--expiration date, effect of--correction or removal, when--public policy regarding devices

1. At least every six months, the director shall test and inspect the measuring devices used by any person selling an average of two hundred or more gallons of gasoline, gasoline-alcohol blends, diesel fuel, heating oil, kerosene, or aviation turbine fuel per month at either retail or wholesale in this state, except marine installations, which shall be tested and inspected at least once per year.

2. The manufacturer's expiration date on motor fuel pump nozzles, hoses, and hose breakaway equipment shall not be the sole factor in requiring the repair or replacement of such devices and equipment nor in the issuance of any fine, penalty, or punishment by the state or any political subdivision. The manufacturer's expiration date on motor fuel pump nozzles, hoses, and hose breakaway equipment shall not impose any new or additional liability on the state, political subdivisions, motor fuel retailers, wholesalers, suppliers, and distributors, and the retailers and wholesalers of such devices and equipment.

3. When the director finds that any measuring device does not correctly and accurately register and measure the monetary cost, if applicable, or the volume sold, he shall require the correction, removal, or discontinuance of the same.

4. Notwithstanding any other law or rule to the contrary, it has been and continues to be the public policy of this state to prohibit gasoline and diesel motor fuel in a retail sale transaction from being dispensed by any measuring device or equipment that is not approved by the department of agriculture or the National Type Evaluation Program (NTEP). Any automatic volumetric correction device for measuring gasoline, gasoline-alcohol blends, diesel fuel, and diesel fuel-biodiesel blends sold at retail fueling facilities is prohibited by state rule or the automatic adoption or incorporation of national standards or rules unless the device is first specifically authorized and required by state statute.
