Leaking 74 K Jetronic Fuel line

[glenninsandiego]

I have a 1974 911S. The 5 mm line that goes to what I am guessing to be the cold start injector is leaking at the injector fitting. Is there a simple way to repair this?

Are there replacement tubing kits available?

Are there other options to the plastic tubing?

The existing plastic tubing for the main injectors has an outside protective sheath this is cracking off the plastic lines as well.

I am just trying to get the car started for the first time after it has been sitting for years but at some point will be replacing the lines.

Thanks

If you are into diy here is a good thread on Rennlist to check out.


DIY Nylon Core Fuel Lines - Rennlist Discussion Forums

Also D&S Sales is a good source for CIS lines and fittings.

That is the line to your Warm Up Regulator (WUR).
It may just not be seated correctly on the fitting.
This thread has some good links in it you should familiarize yourself with.
CIS Out For Rebuild

Search for posts by boxsterGT (Len Cummings) he can likely help you out with all your CIS fuel lines if they are indeed bad.
The rubber coating coming off is not a real big deal, the lines underneath are very tough.

Great threads!

And a word of warning: Please don't continue to attempt running the car until you've got your fuel lines "tight" and not leaking fuel. The pressures on some of those lines is high, and a fuel spray is a good precursor to fire.

That line is available through our host also for around $80 if I remember correctly. I just bought one.

Here's a custom set of Injector Lines I made up for a Concours 73.5 911T recently........

Glenn-

You should have the FD to WUR Line today. I hope it works out.

Have a great Porsche day.
