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.

When formulating these plastic lines, I wonder if Ethanol was taken into consideration. (IMG:style_emoticons/default/idea.gif)

Debated to death! (IMG:style_emoticons/default/headbang.gif)
But (IMG:style_emoticons/default/agree.gif) that is probably the best point I've heard for replacement since you'll find even your local FLAPS now carries 2 types of rubber fuel line, the newest, engineered to withstand the supposed corrosive properties that Ethanol introduces.

Ive pulled out quite a few fuel lines sets ...
3 OE types to be Found:
Early- as stated, complete opaque plastic end to end.
Mid- (again as stated) the 18" or so protruding under the tank are tipped with curved, plated and barbed mild steel tubes.
Late- (75-76) same as described above but changed to a non-opaque black material with presumably hi-pressure qualities since the pump is now relocated upstream of these lines by the factory.

More often than not the lines are found to be in decent, flexible shape ...UNTIL they exit the firewall, at which point the heat from the eng. bay & exposure to elements tends to take their toll resulting (sometimes) in the brittle condition complained of.

Is it a good idea, sure! Is it essential, not always. (IMG:style_emoticons/default/stirthepot.gif)
