I'm trying to resolve some confusion I've run into before I go to
install my new Temp II sensor.  Ken Wilford, of vanagain.com, excels at
reminding customers of ancilliary parts that they will need when
performing certain jobs on their Vanagons.  One part that he recommends
is the o-ring for the Temp II sensor.  The part number is N90316802.  I
can't find this part in ETKA.  The Bus Depot, where I purchased my
sensor, based on cost, claims to not be aware of the need for this
o-ring, and I quote, "As far as we know, the sensor does not take an
o-ring".  In the interest of helping our vendors help us better, can
someone on the list help clarify this situation for me?  Does the sensor
require an o-ring, or some kind of seal?

As usual, thanks in advance for y'all's help (Stan, I can say this, I'm
in Virginia!  :^) )
