Noted the hose talk about what I suspect is that 4" coupler that has two
different diameters.  I had one of these get soft and the lokel yokel VW guy
said "$40".  I taped mine and went looking.  In Tuscon AZ a local family owned
shop looked it up for me.  (Little Germany is the company) and pointed me to the
local Tuscon VW/Honda/Buick/Hotpoint/John Deere dealer, actually some fine
folks.  Their name begins with a B but I cant' recall the spelling.  They're on
Speedway Drive.  These folks had the hose at ~11$US.  They do mail order.

Try calling Little Germany in Tuscon AZ and have their excellent folk look up
the part and order 2.

It's appalling how much the VW Droids expect to be able to gouge the average
loyal customer on parts.  Of course it would be easier to contact Kyle, Ron, or
others on the wire.  I try Kyle first, he's closer.

Happy hosing....
