windshield washer pump replacement procedure?

[nde264 at lulu.it.northwestern.edu]

The windshield washer pump on my 89 90q has died.  I have checked the archives
regarding replacement, and see that the check valve between the pump and the
nozzles clogs sometimes and prevents flow.  However, when I pull the switch to
wash the windshield, there is no noise from the pump, and no flow.  If I turn
on the lights, though, I can get the headlight washer pump to run and clean the
headlights.  I have a new pump, and now I'm trying to determine the method to
replace it.

How do I get to the pump to replace it (I'll check/clean/remove the check valve
as well)?  The filler cap/hose looks as if it goes into the body away from the
engine compartment.  Do I need to remove the hydraulic fluid reservoir to get
at the washer fluid reservoir?

Also, is anyone from the Chicago/Milwaukee area going to be racing at the rally
listed on www.w-a-g.org this Sunday?  I'd like to go, but can't find any
friends that want to help me to suck some life out of my car.

TIA,
