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 the pump from my car
