First, I have to respectfully and emphatically disagree with Mike Miller on
using a hardware store supplied plastic water pipe cap on the Westy Fresh
Water Tank Drain Pipe.  12 years ago I made this mistake that cost me dearly
when I had try to find a another tank because the SAE sized cap and threads
literally obliterated the drain pipe threads which are both metric.

VW 253 070 285 - 34mm -
Parts Fiche (ignore ETKA) says 80 thru 85, but I've encountered this size up
thru early 88 models.
VW 255 070 802 B - 35mm
Parts Fiche (again ignore ETKA) says 86-91, but again, I've found this to be
pretty spotty thru 88, but quite consistent on 89-91 tank pipes.

Both are sadly obsolete by VW & Westfalia (Hella actually made the 34mm
variety) and new or used ones are both very expensive and hard to find these
days.  Chris Turner ( JordanVW@aol.com ) has posted on this list that the
34mm variety can be subtituted with the Vanagon Rear Wiper/Washer Bottle Cap
that used the identical size and thread pattern.  Last I heard, he's got a
coffee can full of good used ones of these.  I happen to have a very small
stash of correct 34mm caps (new,) but these aren't cheap ($29).  Haven't had
any 35mm caps for a couple of years now, but I keep my eyes peeled for
them.  Last I heard, Terry K ( ctonline@webtv.net ) had a stash of these
(about $25-$35 I think), but it's been awhile since I cruised his website.
