183.538 - Metallic fuel line materials.
Each metallic fuel line connecting the fuel tank with the fuel inlet connection on the engine must: (a) Be made of seamless annealed copper, nickel copper, or copper-nickel; and (b) Except for corrugated flexible fuel line, have a minimum wall thickness of 0.029 inches.
183.540 - Hoses: Standards and markings.
(a) USCG Type A1 hose means hose that meets the performance requirements of: (1) SAE Standard J1527DEC85, Class 1 and the fire test in 183.590; or (2) Underwriters' Laboratories, Inc. (UL) Standard 1114.
(b) USCG Type A2 hose means hose that meets the performance requirements of SAE Standard J1527DEC85, Class 2 and the fire test in 183.590; (c) USCG Type B1 hose means hose that meets the performance requirements of SAE Standard J1527DEC85, Class 1.
(d) USCG Type B2 hose means hose that meets the performance requirements of SAE Standard J1527DEC85, Class 2.
Note: SAE Class 1 hose has a permeation rating of 100 grams or less fuel loss per square meter of interior surface in 24 hours.
SAE Class 2 hose has a permeation rating of 300 grams or less fuel loss per square meter of interior surface in 24 hours.
(e) Each USCG Type A1, USCG Type A2, USCG Type B1, and USCG Type B2 hose must be identified by the manufacturer by a marking on the hose.
(f) Each marking must contain the following information in English: (1) The statement USCG TYPE (insert A1 or A2 or B1 or B2).
(2) The year in which the hose was manufactured.
(3) The manufacturer's name or registered trademark.
(g) Each character must be block capital letters and numerals that are at least one eighth-inch high.
(h) Each marking must be permanent, legible, and on the outside of the hose at intervals of 12 inches or less.
183.542 - Fuel systems.
(a) Each fuel system in a boat must have been tested by the boat manufacturer and not leak when subjected to the greater of the following pressures: (1) Three pounds per square inch; or (2) One and one-half times the pressure created in the lowest part of the fuel system when it is filled to the level of overflow with fuel.
(b) The test pressure shall be obtained with air or inert gas.

183.558 - Hoses and connections.
(a) Each hose used between the fuel pump and the carburetor must be USCG Type A1 hose.
(b) Each hose used (1) For a vent line or fill line must be: (i) USCG Type A1 or USCG Type A2; or (ii) USCG Type B1 or USCG Type B2 if no more than five ounces of fuel is discharged in 2 1/2 minutes when: (A) The hose is severed at the point where maximum drainage of fuel would occur, (B) The boat is in its static floating position, and (C) The fuel system is filled to the capacity market on the tank label under 183.514(b)(3).
(2) From the fuel tank to the fuel inlet connection on the engine must be: (i) USCG Type A1; or (ii) USCG Type B1 if no more than five ounces of fuel is discharged in 2 1/2 minutes when: (A) The hose is severed at the point where maximum drainage of fuel would occur, (B) The boat is in its static floating position, and (C) The fuel system is filled to the capacity marked on the tank label under 183.514(b)(3).
(c) Each hose must be secured by: (1) A swaged sleeve; (2) A sleeve and threaded insert; or (3) A hose clamp.
(d) The inside diameter of a hose must not exceed the actual minor outside diameter of the connecting spud, pipe, or fitting by more than the distance shown in Table 8.
Table 8 If minor The inside diameter of the hose outside must not exceed the minor outside diameter of diameter of the connecting spud, the connecting pipe, or hose fitting by more spud, pipe, or than the following distance: fitting is_ Less than \3/8\ 0.020 in.
in \3/8\ in. to0.035 in.
in Greater than 1 0.065 in.

183.562 - Metallic fuel lines.
(a) Each metallic fuel line that is mounted to the boat structure must be connected to the engine by a flexible fuel line.
(b) Each metallic fuel line must be attached to the boat's structure within four inches of its connection to a flexible fuel line.
