(b) Each hose in the tank fill system must be secured to a pipe,
spud, or hose fitting by:
(1) A swaged sleeve;
(2) A sleeve and threaded insert; or
(3) Two adjacent metallic hose clamps that do not depend solely on
the spring tension of the clamps for compressive force.
(c) Each hose clamp in the tank fill system must be used with a hose
designed for clamps.
(d) Hose clamps used in the tank fill system must:
(1) Have a minimum nominal band width of at least one-half inch; and
(2) Be over the hose and the spud, pipe, or hose fitting.


I find it interesting that, as soon as that fuel line gets under the outboard

from the factory.
