I noticed one end has a "fat lip" and want to make sure I orient it correctly. I looked in the PET, WSM, and searched and didn't see anything.




In the pic, the right side of the sleeve has a larger lip depth after the O-ring.

But here's the part you want to know:

"Like so many other parts in this area, the connector pipe was updated by Porsche. The original pipe is not symmetrical – the o-ring grove is closer to the end on one side. With the updated part (951 107 152 03), the o-ring groove is in the same location on both ends. The part was updated because the o-ring would not always reach into the housing deep enough for the o-ring to seal. To ensure this will not be a problem, it is important to install the pipe all the way into the housing. If you are using the old non-symmetrical pipe, the end with the groove closer to the end should go in the housing. The other end goes in the block. This allows the o-ring to get a good grip on the housing. When installing the housing, be sure not to let the pipe pull out of the housing. If you need to pull back on the housing once it is plugged into the plug, be sure to pull it all the way out and fully reseat the connector pipe into the housing. To be safe, it is probably worthwhile ordering the updated connector pipe (which is all that Porsche now sells), for added peace of mind. Also, there was a technical service bulletin 19105, which suggests installing washer part 928 107 166 00 in the block port, using Locktite 638, if the port measured more than 14.2mm deep. This was obviously another attempt to keep the connector pipe seated deeply enough in the housing for the o-ring to seal. Using the updated connector and taking care to ensure it remains fully seated in the housing during installation appears to be sufficient for a good seal, however. "

Wow that was an excellent response.

Solid! Thanks Tom, roger that.
