Partial SS fuel lines?, Does anyone actually make these? Options

[porkchopexpress]

The more I read this forum the more intimidated I get about asking questions! The wealth of information on here is staggering, as well as the dedication and love to this car.

That being said, I have a question that has stumped me a bit. As I have been investigating my car, I found that the fuel line ports that extend into the front of the car under the gast tank are SS. At the tunnel inspection point I can tell they are SS as well. But at the firewall where they exit the tunnel, the lines are plastic. I have found a few vendors that sell the SS lines and they all seem to be SS all the way out of the tunnel into the engine bay.

Has anyone ever heard of this? (IMG:style_emoticons/default/confused24.gif)
I am at work now and only have a pic of the lines into the engine bay. I will post others of the front bay under the tank and the view from the tunnel this evening.

Whatever material was used, the Germans did it right for them to last as long as they have. The crumbling is probably from the heat of the engine compartment as the middle section of the lines remains flexible.

I have seen 3 setups on these cars:

1.) Early ... no metal lines thru the bulkhead ... all plastic

2.) Later including '74 ... metal line thru bulkhead ... plastic the rest of the way

3.) '75 - '76 ... black plastic all the way, same size feed and return line ... material is similar to that used on the 911 CIS systems ... tough shit!

As far a ethanol is concerned, I don't think it attacks plastic formulations ... only rubber. And yes, the V1 & V2 were ethanol powered hence their lack of success in winning the Battle of Britian (IMG:style_emoticons/default/av-943.gif)

And they say this isn't Rocket Science! I bought a 25 foot length of high pressure stainless brake/fuel line from Jegs and silver soldered/brazed solid ends on. Very easy, used a map gas torch. The brazing rod is pricy, but I used less than half a rod.
