In regards to the expansion tank for your Volkswagen
Vanagon you
recently
purchased from us on ebay: When a company makes a mold
to manufacture
parts
for the automotive industry, they grind marks in the
mold so those
marks
will show on the surface of the finished product to
identify the mold
from
which the particular part was made.  The markings they
use to identify
the
mold are sometimes (and sometimes not) the part number
under which the
part
is going to be sold by the parent automobile company
(in this case
Volkswagen of America).  As time passes and the
vehicle manufacturer
(Volkswagen) makes changes to their part numbering
system, the parts
manufacturers do not go to the great expense of
remaking all of their
molds
just to reflect changes Volkswagen has made in their
numbering system.
These changes made in a numbering system are known in
the industry as
�supersessions.�

The current and only part number for the expansion
tank on your Vanagon
was
superseded years ago in the Volkswagen Part Numbering
System to: 025
121 403
B.  Nothing has changed in the physical shape or
functionality of the
tank,
it is the same tank that was on the first Vanagon that
rolled off the
assembly line for model year 1986.  It fits 1986
through 1991 Vanagons
and
1986 through 1991 Vanagon Syncro�s.  All they changed
is the number
they
decided to sell it under.

Volkswagen has more than one supplier for most of
their parts.  We have
no
way of knowing which manufacturer makes a particular
part on our
shelves nor
what kind of identifying marks they may have ground in
their mold.
Therefore, the only way we sell, describe and ship
parts are by their
current number in the Volkswagen Part Numbering
System.  This number
can be
and usually is totally unrelated to any mold or
casting marks that may
be
have placed on the mold or stamping die when the mold
or die was made.

What is important;  we advertised a 025 121 403 B
expansion tank for a
1986
through 1991 Volkswagen Vanagon and that is what you
received.  Even
more
important from your viewpoint, regardless of what the
markings made by
the
mold on the tank may have been, it was the correct
part for your
vehicle, it
fit and did the job for which it was intended.

We appreciate your business.

JoAnn
