I don't know about the 79 Spider but if you look in the picture here:

Item 41 is the washer fluid tank on the S3 Spider. To the left of the tank, against the firewall you can see a white/tan/beige line which connects the pump mounted on the bottom of the tank to the washer jets in the cowl via that line.

I would expect that you should find something similar on the 79 or perhaps the broken end of a piece of tubing. You may have to remove the cowl and replumb the washer jets to your pump

 

86spider, thank you! I found a hole where the hose will go and I see an end of a hose in the cowl vents. So, knowing that removing the cowl and replumbing is out of my league....looks like a trip to the $hop.... Thank you, though

 

It is not very hard to remove the cowl vent piece. Remove the windshield wiper arms. I think you have to remove a nut under each wiper post next. Lift up the rubber flap where the hood closes and find a few small screws. Remove them and the cowl vent piece slides out forwards. There should be some clips along the base of the windshield frame - you might need an extra pair of hands to help get the cowl vent back into place into those clips.

Its really easy to do. Just did it myself last week

 

have done this a few times myself too.......very simple job....and if you do it yourself there are a few things to do whilst you are in there....cleaning out any leaves, making sure the cowl hoses are free of crud, lubricating the wiper linkages, checking rust below the screen, cleaning up the screen clips, etc....things a shop will not do (unless you instruct them and pay them to do so)

 

Wowwww! You guys make it sound so easy!!!I is full of leaves for sure. And there is an open end of a hose I see. The hole I spoke of MAY be a drain hole?

I'd love to post pics in the thread but I can't seem to figure that out either. Can't upload pics from computer? Do they have to be in an online storage somewhere? Hmmm...more things to work on

 

its very easy to post photos:
click on "Go advanced" button just below the "quick reply" window, that opens a window where you now can see a "paperclip" icon (next to smiley), click on this and it opens a further window where you can choose pics from your computor... when pics have uploaded (you see the source appear when they have) then close window and they should be in your reply (to double check, you can click on "preview post" before submitting reply)

 

For some reason the 'paperclip' icon isn't working right now. After clicking 'New Reply' scroll down below the text box to find the 'manage attachments' button.

Here's some pictures about how to attach pictures...

 

Lets see if this works (no paper clip icon present). Thank you ghnl!!!! OK, now we are getting somewhere!!!

 

does your 79 have an electric wash/wipe foot pump?

Off topic, I know, but how odd to see a "red stripe" motronic relay someone's put in place of the fuel cut off switch....first time I have seen that...normally you just join the wires together, if it is removed.

So taking out the reservoir has opened a can of worms. That end of hose was attached somewhere south of the reservoir. I know it was. I had to pull hard to get it out. That aside, now I see a raw end of hose in the cowl. See pic. There is also a cable coming out, a long cable with nothing on the end? Huh???? Car guy didn't know what it was.....sigh.....My washer spray works by pulling wiper arm. But now motor isn't working (and I swear it was before I took it all apart) Is there a way to test the motor NOT plugged into car? Worms, worms, worms!!

 

Ok, so I took the pump to autozone and they tested it.....dead. So even if I figured out how to get it all back together, it would be moot as the pump doesn't work.

 

Is that "cable" more like a nylon rope???? I'm trying to figure out what this is for on my '81 Spider. It seems to run down parallel to the fuel lines, but it's been cut about half way under the car (presumably when the car was converted to carbs from Spica??). Anyone??

 

Got it! Actually it's a metal braided cable. Goes (went) to the exhaust overtemp thermocouple. Connects to a fused plate under the glovebox. See http://www.alfabb.com/bb/forums/spider-1966-up/193354-fuse-under-glove-box.html
