I need the Bosch part number for the 3 port 914-4 pump and the 914-6 pump. I have some 005 and 009 pumps. The number I have for the -4 pump is 0 580 463 005. Also showing the 914-6 part number to be 0 580 960 009. I have some pumps going for total restoration trying to make sure what I have.

Mark...where are you sending pumps for "total" restoration and have you found any gaskets that work for leaking pumps?
Thanks
