No deliveries shall be made in excess of the marker capacity
of the truck or compartment. Every driver of a vehicle tank used as
a measure shall have in his possession, and present to the representative
upon request, the calibration chart for the truck from which he is
delivering fuel oil, together with the loading tickets and delivery
tickets for the current day.
All fuel oils with a temperature greater than 60° F.
shall be sold, offered for sale or delivered on a basis of a temperature
reading of 60° F. A tolerance of 25° F. will be
permitted for No. 4 and No. 6 oils. A tolerance of 10° F.
will be permitted for No. 2 oil.
Vehicle tanks equipped with meters shall have no bypass or other
device or mechanism attached thereto by which any measured liquid
can be diverted from the measuring chamber of the meter or the discharge
line therefrom.
Vehicle tanks equipped with meters shall be provided with a
mechanical air eliminator adjacent the meter inlet and shall be so
equipped as to prevent air or an emulsion of air and oil from passing
through the meter and/or being delivered to the consumer. The vent
from the air eliminator shall terminate in the nearest compartment
not more than one inch below the top of the compartment. The vent
shall be of rigid material and shall be of the largest size that can
be accommodated in the fitting on the air-eliminator housing, as designed
by the manufacturer. No device shall be provided or used to shut off
or otherwise obstruct such vent.
When fuel is purchased for resale, or is sold, offered for sale
or delivered directly to the public by the dealer or owner of a fuel
oil bulk plant, the operator of the vehicle transporting or delivering
such oil shall retain in his possession during such transportation
or delivery and shall exhibit to a representative, upon request, a
ticket commonly known as a "loading ticket," which must be issued
by the seller or his agent, and which shall indicate the grade of
fuel oil as well as the quantity. If the temperature of the oil is
above 60° F., a volumetric correction to 60° F.,
must be made. A tolerance of 25° F. will be permitted for
No. 4 and No. 6 oils. A tolerance of 10° F. will be permitted
for No. 2 oil.
A retail petroleum product device of the meter type shall be
so constructed that after a particular delivery cycle has been completed
by movement of the starting lever to its shutoff position, an effective
automatic interlock will prevent a subsequent delivery being started
until the indicating elements have been returned to their correct
zero positions.
