I have a 90 RS with the washer nozzles on the wiper arms. When i got the car there was no pump or hose going to these, now I'm trying to put it all back together. My problem is I have no idea how to route the hose. There is a hole in the firewall to the right of the wiper motor (when looking towards the firewall from the front of the car)I assume the hose runs from the resevoir through this hole into the area where the wiper arm linkage is then Tee's off in there. When I run the hose there it makes contact withe the wiper arm linkage whe I turn on the wipers. Is there another way to route the hose. Also to the right of the plastic screen cover (looking from the front of the car again) there is a hole in the deck about 3/8" or so that leads down into the linkage area, any idea what that is for. I know it is not for the washer hose as the hose comes out through a hole in the plastic which covers the linkage. If there re any pictures of this setup I would appreciate it.

Thanks

 

The hole is actually next the brake vacuum booster..
there should be plenty of room in the cowl to route the hose so it does not contact the wiper arm.
