It's unfortunate to say but my C-GT has been back in the shop since the engine out service. It appears I have a vacuum leak related to the fuel pump which is in the fuel cell and you all know where that is located.... I'll keep you posted but certainly not expected at 5,900 miles...

Hoping your issue is not related, but my dealer relayed info from PCNA tech center about ethanol content of fuel causing fuel pump diaphragm deterioration which is only cured by replacing entire fuel tank with integrated pump assembly ($$$$). They recommend Sta-Bil or equivalent enthanol treatment added to the fuel to forestall such problems during long term storage.
Peter, I hope this gets sorted out. It's been a pleasure to follow this thread.

Burning Brakes
Amazing thread! Thank you Peter and Jimmy for sharing this with us. Quick question, why did the shocks need to be replaced? With only 5,900 miles, unless the car was a Track rat, which I highly doubt, I can't imagine the shocks going bad. Also, are they not rebuild-able, or is it almost as expensive to rebuild these shocks as it is to buy new ones? Good luck to you guys on getting the fuel tank/pump situation sorted.

I had porsche replace my front and rear shocks, the car had 10k miles and was 4 years old at the time. The top seal on the shaft leaks. This seems to be a common problem.. like coils, etc.
Since it was after a major, we re-checked the suspension and tried all sorts of things to identify the noise location. Carbon is a nice transmitter for sound, making it difficult to isolate. In the front you might see drops on the chassis. In the rear you can reach under the shock and feel for fluids. or listen for a clunk sound!
We test drove another customers CGT (Orange Lambo coloured one) and found that he had bad front shocks. Once you hear/know the sound you can identify it.

Bummer about the diaphragm in the fuel pump, it's getting harder and harder to find non-ethanol fuel, especially 91 or 93 octane.
As others have said, remarkable thread. Just as a casual observer, is the starter ring on the clutch unique to the Carrera GT? Obviously I have never worked on this caliber of car before, but I've never come across a starter ring like that - most I've dealt with have just engaged the flywheel directly, which is obviously not possible in this application.

I had this happen on my car early after i received it; due to lack of use from prior owner the seal on one of the shocks hardened and leaked oil, requiring replacement.

Update on my replacement fuel cell/fuel pump assembly......
Fuel pump evap issue was diagnosed in June/July 2015. Fuel cell replacement was to be delivered from Germany in October. They gave me the option of sending my fuel cell back for repair but the net time for that would have been similar to the new replacement in October.....
October came and went.... New ETA was January 2016, spoke with PCNA and they explained the issue as not having any of the original fuel cells left from the original builds in 04-05. They no longer worked with that supplier, new tooling, manufacturing, testing, retesting and certification needed to take place with the new vendor hence the long delay.....
January is here and now delivery for the new fuel cell is April/May at the very earliest.... At this point we have made the decision to remove the original fuel cell and send it back for proper repairs. Which ever cell is ready first (rebuild or new) will be the one installed......
In hindsight we should have made this call last year in June...
The frustration level has been very high and though I appreciate Porsche staying in close contact with me I would lie if I said I'm not very disappointed for the constant delays. I'm sure they will carry inventory to avoid this problem for others in the future.
Hope to have the car ready for late spring early summer again.
