My understanding is that the metal ring prevents the hose from expanding
and therefore it cannot slip off.  I read that somewhere.  I reused them
on mine and all seems well 4 years latter.

Benny- I noticed in the diagrams that the small piece of hose attached
to
the fuel injector does not appear to have a hose clamp on it, just that
metal ring.
But- the metal ring doesn't appear to "clamp" the hose to the injector.
Your repair shows a hose clamp *and* the ring installed on the injector.

What gives? Is the metal ring doing anything?
