WTB 81-84 w126/w201 door lock vaccum pump
 

#126 800 0348 or #000 800 0348

Pick and Pull charges $6.99 (if I could find one) and a google search shows new ones available for $172.80. Id be happy to pay $30 for a good used one if anyone has a working one they would sell.

I have one I pulled from my parts car before I scrapped it, still sitting in the garage.

I have no idea what it'd cost to ship to wherever you are though, so you might be money ahead to get one from Pick N Pull.

I am in California (95687). As long as it still works paying shipping is probably cheaper than 3-4 gallons of diesel to drive to any pick and pull that has the right car.

Check the connector to make sure it is compatible. The earlier SD's vac pump had a two wire connector and the later ones had 3. Make sure it will mate up with your SD.

The part numbers I posted are the correct ones for my car, it has a single 3 wire plug.

That should work. I just purchased one for an 81 SD and was sent the wrong one because I did not give them the stock number. They replaced it with the proper one with no static and it works fine.

Let us know how it goes. I think I paid about $100.

I'll have to look at what part number is on the pump I salvaged, as well as powering it up to see if it actually works.
I pulled it from a front end collision car that I bought for the power train, and then salvaged just about every thing else from before letting the wreckers have it.

If need be, I can also check the local Picknpull for you, as we have one only a couple of miles from where I am.

I've got one sitting in my parts bin. I'm in 95667, Placerville. Where are you?

In in Vacaville. It would still probably be cheaper to send it though.

Whoops! Sorry! Mine has the 2 prong plug.

That's why we try to keep an eye out for each other. Just saved some shipping charges.
