Is there a way to find out hose size from porsche part numbers?
 
I'm redoing a lot of things on my CIS system, and instead of spending $20-30 for a small piece of hose, I'd like to just order a fair amount of each size, braided, from meyle for 1/4 of the price.

Here are some of the part numbers I'm wanting to replace, but I don't know the size of the hoses. I could try measuring them with calipers but they're sorta of dried out so...

99918116750

n0203591

Anybody have any ideas?

I just zoomed in on the photos of the parts in the catalog.

99918116750 looks to be 4.5x3mm

n0203591 looks to be 9x2.5mm

The hose appears to be NBR rubber which has poor compatibility with ethanol.

Be sure you select a hose material that is ok with the current ethanol fuels.

Hello AAdvanced,

I'm replacing 999-181-167-50 too, so I'm wondering where you landed on this. I have 2 areas, from the cruise control and from the intake to the recirculating air valve.

Thanks!

The PET for your year car will show the hose diameters and lengths. If you have not downloaded the PET for your car, do it now.

You wont go to Porsche heaven if you don't buy official Porsche hose. But seriously, it's time consuming to find the right sizes, especially the very small diameter stuff. I found some cheaper alternatives, but the shipping always killed me so it seemed between the time spent, the shipping charges and the longer lead time to ship, it wasn't worth it. To make it more economic I bought extra length unless it was a specific hose length and I keep it on hand for when I need a section.
