No, I added the metal filter.  I made a bracket similar to the VW style and
mounted it right after the pump.  I actually ordered it before I crawled
under the '85 and lo and behold, no metal filter!  It does show up as an
'85 item and I ordered it as such from Bus Depot.  I used a generic plastic
filter on the inlet side.  BTW, if you add this metal filter, remember to
use the high pressure (FI) gas line!  I figured it couldn't hurt having
this second filter.  It is large and should last  forever. VW wouldn't have
added it if they didn't see a real need.    As far as fuel pump noise, I
replaced the one on my '86 and it was noisy (brand new from The Parts
Place--sorry Melissa, didn't know any better.)  The one in my '85 that the
PO just replaced (I have the receipt from the local VW dealer) is noisy and
this is a second  one!  The dealer replaced the first one because it was
too loud.
