Headlight fluid pump connection leak question

[daway]

sorry i wrote H20 and i meant fluid (can not edit)

2001 3.0i production date 9/00

Seems to be org. pump works perfect.

I noticed a week ago that my headlight pump connection piece was leaking washer fluid (part number 668360181, in picture white color, in between hose and headlight pump) and i thought it was coming from were you squeeze the black part down to clap it to the pump.

Today i put on the new connection piece and i noticed it was still leaking (w/in mins and tested for about 2 hours w/ paper towel) around the end of the connection piece on the pump side and not making a good seal around the pump. Now i wonder if the pump side is just worn down (were the white connection piece mounts to) which is not making a good seal and i need to buy a new pump to stop this leak. I looked up the headlight pump and BMW stop the production of that pump (part number 67128377613) and replaced it with this ES#184159 (got this number by google'n the old part number) and was wondering if the new pump style seals better...

Has anyone had this issue? It is leaking a good amount over night...i put a white paper towel under the area...


Another question:
In the service manual it states to use a anti-friction agent to the base of the pump when replacing it. What is a good anti-friction product.
