Jeff,
Good points! I always wondered why Porsche didn't change them out. They must have tested them to some engineering standards and found them to be satisfactory. My 76 has black plastic. Did the later years change to a different plastic or is it just a different color?
Thanks,
Tom

The 75-76's used black Nylon 11 lines. Same stuff, different color. By the way, the engine (Hose) end of the lines have beaded metal reinforcements inside them due to the higher working pressures.

Hey John, to be clear, we are talking about the engine bay tubing sections passing through the engine tin. The 1970-74 tubing was definitely milky white/clear. Are you saying the engine bay tubing for the late cars was black? I have not seen that...Can you post a photo?

I know the 1975-76 center tunnel tubing was black.

The plastic line we pulled out of my '75 were still fairly flexible. I've seen some early ones that were stiff and brittle.

In '75-'76 the tubing was definitely black. They were made of a different material as well, I believe the name was Teclamyte. Still have a small piece laying around somewhere but can't find it. Supposedly it was more flexible and durable. When I swap my tunnel lines for the Tangerine ones I'll post pics...

Hey Jeff,

I just looked at the pictures of my 75 2.0 (long sold). The fuel lines in the engine compartment were black. I will send you 2 pictures via email.

Jeff,
Here are pics of mine. As far as I can see, they are one single piece from the front pump to the engine hose connection.
John, thanks for the info. Mine are still pretty flexable. They don't seem brittle at all. I did notice the metal pieces when I had the engine out.
Tom

The material I use is T304 seamed tubing.
Seamless would be a waste of money in this case, as the pressure rating of the seamed tubing far exceeds the pressure in any 914 fuel system.

T304 stainless steel is more resistant to wear than nylon from chafing on steel or other hard materials.
T304 stainless steel resists battery acid much better than Nylon11.
In my shop we've seen late model black nylon lines pitted by battery acid to the point of failure.

In my experience, most early cars have already lost the OE engine compartment lines to embrittlement or acid failure.
That's why the majority of people who purchase my stainless lines don't even know their car had hard plastic engine compartment lines.

I see nothing wrong with replacing them with oem materials but the service interval will be much shorter than stainless IMO.

There are no "Tunnel Lines" and "Engine Compartment Lines" in the 75-76's, There are just one piece lines from the front bulkhead to the rubber hoses at the engine.

Wow. Look at what happened to my little WTB thread! (IMG:style_emoticons/default/w00t.gif)

I'm new to these forums but I learn fast that the best way to learn about a 914 part or system is to place a WTB for it! (IMG:style_emoticons/default/av-943.gif)

I appreciate all the shared info on the fuel lines and I'm sure Jeff appreciate the extra sales. When his set arrives on my doorstep I' ll take some pictures of them from the box and in the car and what I think of them compare to stock.

Just Wondering: Would it be possible to attach the new tubing to the old tubing and gently pull out the old tubing and the new tubing would be in place? Wish that was the case!

I have my car apart and am getting ready to run new lines through the tunnel once I decide on rather to go with Jeff's "New" plastic or Stainless. Anyone know of a good old thread that shows how to replace the lines through the tunnel? I know there must be at least 2 or 3.

Awe Hell, plastic is fine.

In fact the "Hell-Hath-No-Fury like a Roasting Teener" is being judged over on isle 6 as we speak. The plastic will make you a shoe in for the grand prize;-P

Actually Jeff, it seems there was a recall on the lines in addition to the battery cover. I am actually working with Brumos right now to get to the bottom of this recall. There was a kit available, including replacement fuel lines. What they were and what kind, are unknown at this point. Brumos is trying to find out, but they, USA headquarters in ATL and Germany do not know as of yet.

I included specifics from Porsche at the time of the recall in the introductory post in this battery thread I started:

http://www.914world.com/bbs2/index.php?showtopic=203921

If I may throw my two cents in, for those of you who want to remain plastic for whatever reason (I see the argument of pros and cons on both sides, and Jeff did bring up some good points to look out for), if the 75 and 76 models did come with black lines, it might be better to switch to the white or clear lines for a very important reason - the white and clear lines will show visible signs of age when the time comes (yellowing, browning, cracking, etc.). The black lines will camouflage and discoloration, appearing normal. Better to see the effects of them getting old to know when to change them.
