(1) Fuel tank manufacturer’s name (or
logo) and address.
(2) Month (or lot number) and year of manufacture.
(3) Capacity in U.S. gallons.
(4) Material of construction.
(5) The pressure the tank is designed to withstand
without leaking.

Sec. 183.516—Cellular plastic used
to encase fuel tanks
(a) Cellular plastic used to encase metallic
fuel tanks must:
(1) Not change volume by more than five percent
or dissolve after being immersed in any of the following
liquids for 24 hours at 29 deg. C:
(i) Reference fuel B ASTM D 471 (incorporated
by reference, see Sec. 183.5).
(ii) No. 2 reference oil of ASTM D 471 (incorporated
by reference, see Sec. 183.5).
(iii) Five percent solution of trisodium
phosphate in water; and
(2) Not absorb more than 0.12 pound of water
per square foot of cut surface, measure under Military Specification
MIL P-21929B.
(b) Non-polyurethane cellular plastic used to
encase metallic fuel tanks must have a compressive strength
of at least 60 pounds per square inch at ten percent deflection

Sec. 183.5), “Compressive Strength of Rigid Cellular
Plastics”.
(c) Polyurethane cellular plastic used to encase
metallic fuel tanks must have a density of at least 2.0 pounds

(b) Each vent must:
(1) Have a flame arrester that can be cleaned
unless the vent is itself a flame arrestor; and
(2) Not allow a fuel overflow at the rate
of up to two gallons per minute to enter the boat.
