Door lock pump question

If I can get some time this weekend I am going to try to go to PnP but I am confused about what pumps I can use. I looked at the EPC site and these are the pumps they listed for a 126
1) 126 800 03 48
2) 126 800 04 48 - This is what I have in the car now
3) 000 800 02 48
4) 124 800 01 48
5) 124 800 09 48

Also I tried a 0-132-006-300 and it worked but not as well as I would like.

Does anyone know what the difference is between all these pumps?

I know the one in the car uses a pressure switch to turn it off and to switch from pressure to vacuum and the other one that I tried uses a timer to do that but what about the rest of them?

Does anyone have a pump they want to sell?

If the price is right I would be interested in none working pumps also just so I can take them apart to find out what the difference is.

This is a picture of the pump that came from my car.

The first set of two number in MB part numbers refers to the versions of the part. An upgraded part will have a different set of those two numbers but it's still the same part, and each version should be able to replace any of the other versions. So if you find a pump with any of those numbers they should work.

Phil - they are not the same. For my 81 300SD I needed a 126 800 04 48 lke yours. SVMBZ sent me a 123 800 003 and it would not work because the electrical connection was different. Then they sent me a 126 800 05 048. It works but the shape is a little different; had to stuff it into the rubber covering because it did not fit. Not pretty but it works now.

Could not figure how to edit the msg above. They sent a 126 800 03 48 which had the different electric connection; then sent a 126 800 05 48 which worked. Never able to get the to send a 126 800 04 48.
