(a) Every retail dealer in motor fuel shall publicly display and maintain on each pump or other dispensing device, from which motor fuel is sold, at least 1 sign stating the price per gallon of the motor fuel sold from such pump or device, which price shall be the total price for such motor fuel, including all state and federal taxes. Such sign or signs shall contain no information other than the total price, except the sign or signs may state that the price includes all taxes or may state the amount of taxes included in the price or may include, in addition to the price per gallon, the price in metric units. The statement of the total price, as shown by the figures used in any price computing mechanism constituting a part of any such pump or dispensing device, shall be considered as a sign within the meaning of this section and no other or additional signs stating the price shall be required.

(b) Nothing in this section shall be construed to prohibit other signs stating the price of motor fuel from other locations on or about the premises where motor fuel is sold at retail.

(c) When the price indicated on the computing mechanism of a pump or other dispensing device offering motor fuel for sale is the per gallon price, that is the only price sign required to be displayed on said pump.

(d) When the price indicated on the computing mechanism of a pump is the per liter price, another sign indicating the equivalent price per gallon to the nearest 1/10 cent must be prominently displayed on said pump with numerals no smaller than those which display the liter price. In addition to the unit price, the signs on the pump may indicate that state and federal taxes are included in the unit price. All taxes must be included in the advertised price.

(e) The price indicated on the computing mechanism is the maximum price which may be charged per measured unit and the resulting total cost computed is the maximum remittance that can be demanded from the consumer for the fuel sold.

(f) A cash discount may be offered which is less than the computed cost, but a surcharge for credit, or any other reason, may not be added to the computed cost for the fuel sold.

(g) Separate pumps may be provided for cash and charge sales of the same brand, grade, type of fuel and service, providing that the pumps are adequately and prominently identified.

(h) Price signs displayed on the station premises and not attached to a pump must indicate the grade of fuel, the type of service and the unit, if other than gallon. If there are special requirements to qualify for an advertised price, such as minimum quantities, cash, etc., those requirements must also be prominently included on said sign.

(i) Fractions of a cent on the price advertised must be of the same general design and at least 1/2 the height and width of the numerals representing the whole cents.
