First, I don't know what the noise is.
Second, if you're filling your fuel tank,
and continue to top off the tank after the
pump initially cuts off, stop doing that and
the noise will probably go away. Overfilling
the tank floods the charcoal cannister in the
emission system, and you may be hearing fluid venting out of the cannister.
