I can't seem to find the part number for the (Blue & Black) Vacuum Check Valve, which lives right near the Brake Booster, or the 4-way connector attached to it. Could someone help me out with a Part Number and/or a PET location for these parts? This is for a 83S, 5Spd.

Thanks.

It took me so long to track this part number down. Although it apparently doesn't exist in PET it does acknowledge it if you enter the part number. I sent the OPC crazy for 2 months ordering random valves that looked correct :-) Anyway the one you want is 928.537.361.02

Thanks for the tip Graham. I gave the number to my local Porsche dealer, and he figured out that it does show up on PET, but in a different application. It is still on a 928 though. If you look on the 82MY page 08/04/10 part 30 there is the valve. It is a part of the (vacuum) door locking system. I still can't find a P/N for the 4-way rubber vacuum connector that is right below the aforementioned Vacuum Check Valve on my car though.

You should have asked the first time and saved a trip back to the OPC.
928.574.710.09 is the 4 way. Don't ask how I know this as well :-)
