Re[2]: Windshield Washer

Going by memory here, but I think the spare is supposed to be pressurized to 
42psi.  This added pressure allows the windshield washer system to work properly
yet not create an underinflated spare.  There was a check valve in the system so
when the pressure reached a certain point (30-35psi?) the washer system would no
longer work.  Again, this protected the spare from being emptied of all its air.

I installed an after-market electric pump and am happier with this set up.  My 
Porsche used the same spare tire method so I converted her to an electric pump 
as well.  Though the switch never failed on my Square, water would leak out of 
it onto my leg when it was activated.  That is why I converted to electric.

Here's how it works on my '65, which I believe is the same on your '69:
1. The washer fluid bottle, contained within the front trunk area, is
filled with 1 liter of windshield fluid and pressurized to 36 psi, same as
your slammed low profile tires (yey, I'm a part of the lower/don't lower
insanity)
...
Yes, you read right, fluid goes through the actual switch.  While this
seems to me to be an insane design, I've never seen the switch fail because
of this.  Hmmmm, weird.

Interestingly to note is that Bug windshield bottles were pressurized from
the spare tire, leaving many owners stranded when they got a flat due to
neglect.  They could see real well, though...
