Sanity check, on the tunnel fuel lines Options

[mmichalik]

I went to start changing out my fuel lines with a stainless steel set. When I pulled the tank out, the rubber lines basically feel apart.
I just took the rubber line off of the tunnel line when I noticed that the tunnel line was not plastic. It's what appears to be cadmium plated steel (my magnet stuck to it).
Just as a sanity check, all 914's, particularly a 1974. came with plastic lines down the tunnel, correct? I believe the answer is yes.
If that's the case, I can assume that the tunnel lines have been replaced in the past. They appear to be rust free and clean, should I continue with the Stainless replacement or just leave them there?

How difficult is it to pull the plastic lines out ?
I’m getting ready to do this and want to know about any hard parts to the change over

This was the first time I did it on a car that was still put together (IMG:style_emoticons/default/smile.gif) so it took a little longer than expected.
I had to remove the hood, pull the tank out and disconnect the lines there. Then I had to disconnect the fuel lines in the engine bay. Once that was done, they pulled out easily through the engine bay. All in all, that probably took about 2 hours or more (there was some cursing and a few breaks involved)
Putting them back in as a bit more time consuming because I had to pull out the center console on the car to get to the front toe kick panel in the tunnel. It took me about 2 hours to pull everything out of the cabin (again, because it was my first time) and then about 30 - 45 minutes to feed the line back through.
There was a bit of finagling going on to get the stainless steel line to go through the tunnel and then line up with, and go through, the hole in the grommet in the front.
I still have to put everything back together in the cabin so, I figure another hour or so there.
All in all, I would plan for a full day and just as tip, it would be much easier if you removed the passenger side rear tire AND have someone help you get it through the front grommet.
Also, be careful removing the old fuel line hose clamps. Mine were rusty and stuck tight. I cut my finger pretty nicely when the screw driver slipped out of the slot.
