I was prepping my car to head to the smog station after a 3 years off and on again backdate project:

Started it up and pulled back to find a nice trail of drips. Put my finger in it and smelled fuel. Checked up at the splash shield and it was the high pressure line from the fuel pump. It had failed me before in 2008 and I had it repaired at a known local Porsche shop.
What I found is that , although they used cheap clamps, that wasn't where the leak originated. The hose material itself was disintegrating. This was Continental COHLINE 2134 .0600 fuel injection fuel line. It lasted less than 9 years while the car sat most of the time. Yikes.
I think I will patch it again so that I can drive it, smog it, align it, and wait on new fuel lines. Coincidently, I was just emailing back and forth yesterday and today with Len about new fuel lines...
Be safe out there!
