    Hi Plenum, I have read you may have instructions on how to install the 991 ducktail. Is that correct? If so, would you be willing to share this information with me? Thx!

    Hi Plenum,

    I'm wondering if you have instructions for how to remove the rear interior trim on a C2S 991.1 so that I can access the rear speakers. I have the Burmester system and had rattling in the door from the speakers, which I was able to solve using Dynamat and tightening screws. There's still a slight rattle in the rear areas so I want to know how to remove them.

    Any help you can provide would be much appreciated!

    Hi Jon,
    Sorry to hear that you are selling your C4S.
    Did you find a 350 R?

    Hi plenum!
    Thought ask you since you are very knowledgeable about all this stuff. Have many things you have done........and appreciate the opportunity to learn from you.
    I'd like to take the silver ring and paddle shifters off and get them painted a satin it possible? Asked the dealer but lead mechanic has never done it.
    Thanks? Rob

    Pawel- You didn't leave any way to contact you directly, and since you are not a member on the board I am not sure how you will get this... From what I can tell you really only have one official part # for the OEM fuel pump on the 1998 986 2.5L H6 engine...#996-620-102-00. You can source that specific part from just about any online site, such as Paramount Auto. You may be able to find a better price, but at least this is an OE part with warranty. I can't locate the technical specs on the pump to tell you pressure and such, but I can tell you that this part is listed specific to that year and engine. I'll take a look in some other places to see if I can locate the technical specs specific to the pump, but for now that's all I can offer.

    I hope that you could help me as I'm getting confused and desparate right now

    Basically I diagnosed my fuel pump for Porsche Boxster 986, '1998, 2.5, 204HP, tiptronic was faulty. Right now I'm looking for replacment pump but just the metal inside. The one I took out had a code 1H0 906 091C but now different shops give me different informations on it's specs BAR & L/H and what specs I need (most just say it looks same so it should fit - geee).

    Hopefully U could access that Porsche application that you mentioned you have access to and check the specs for fuel pump for my Porsche Boxster, than I would be able to find a pump matching them and finally order it after 3 days of quoting.

    Thank you very much in advance and Kind Regards
    Pawel Krystek
