I have owned my 78 sc (Euro) for about 4 years now. As far as I am able to determine the car is all original with about 150,000 miles on it. Since buying the car I have been in the throes of raising teenage twin daughters and the car has seen infrequent use; basically I have started it and driven it about 15 miles or so several times a year.

The girls are requiring less of my attention these days and I plan to spend some time with the car. My objective is to end up with a daily driver I can enjoy, drive and polish. I am not interested in increasing performance, just maintaining it in drivable condition and enjoying the luxury of driving the dream car of my youth.

I do intend to remove engine and transmission this spring for the purpose of replacing seals and repairing a couple of small nuisance oil leaks, e.g. oil pressure sensor leak, and clean it up; additionally, as it has the "chain tension-er checks" rather than the Carrera tension-er, I plan to do that upgrade. transmission is 15000 miles off of a professional rebuild.

Presently, the car runs fine with no start-up, idle, or running problems.

After reading through many posts on the board, I have one major issue in mind and it has to do with the stock CIS system. Primarrily, I am concerned about availability of parts such as replacement fuel lines. I figure that, if I am going to go with a different fuel system, the best time to make the change will be this spring when I do the other small things to the engine. My questions are:

1. Is it still possible to obtain everything you need to service the CIS system and keep it running properly?

2. Does the CIS system, aside from the fact that it is ugly, represent the simplest and most reliable fuel injection option for 911sc? I note that in many posts, folks state it is the most intuitive system to diagnose when problems do surface.

3. If not the CIS system, which available system would be the best bet for the mundane 911sc owner who wants to avoid unnecessary complication in installing a new system and wants to avoid unnecessary unreliability once the new system is installed.

4. If I keep the CIS system should I replace the fuel injector lines as a matter or principle or is it worth waiting till they fail?

5. When stock CIS fuel injector lines do fail, what is the usual mode of failure; catastrophically, or small leaks?

I have searched the board but have had some difficulty finding posts that address my specific concerns.

I have heard there are examples of 911sc cars that have logged several hundred thousand miles of operation without major failure, I want to do everything in my power to make my car one of these examples.

Thanks for any help.
