Default PS Pump valve cap
I seem to be missing this cap for what looks like a valve stem size connection on my PS pump. I'm looking to put something over it to keep crud out of there. Does it need to breathe / vent at all or will a rubber cap be just fine?

Well I'm rolling the dice and capping it, if I blow up we'll know that was the wrong call.

Just took a picture of my cap for you...

Looks like it might be designed to vent rather than seal completely. I don't see a separate part number for it on the PET fiche, perhaps your dealer can find the part number for a replacement.

It is a vent cap as pfbz shows. Early cars had a "hose to nowhere"

hmmm, may have to call LA dismantlers or something. Striking out finding one on the internet.

Thanks for the up-close view.

#16 on this Sunset Porsche Parts diagram? If so, maybe they have one in stock.

I think you're right Dock. What diagram did you use though? The ones I'm pulling up for an 03 turbo don't show that cap on their site.

It's from the Sunset Porsche Parts area of their website. I can't imagine that it's a different cap on the '03.

That looks like the right part number...

Might be easier to order from your local dealer (even though the'll likely charge $5 instead of $2) rather than deal with shipping.

My local dealer is Newport Porsche. If you're not buying a 918 they act like you are wasting their time. I'd rather pay the $6 in shipping and support the site that helped Doc and I find the part.
