Ok I'm lost. I have an extra set of steel lines in my tunnel that I cannot explain (they are not placed in a location for fuel, they split and go in opposite directions), put there by a PO. But they are plugged once they exit the firewall. I am not sure where they go in the front trunk. I have the rubber fuel lines that I can trace to my Webers...but they disappear halfway through my tunnel to the front. Where do they go?

Where do the fuel lines route to? And can anybody explain why somebody would install steel lines that are plugged, come out near the shifter, and split in 2 different directions?

And that is a mirror you are looking into.

The original fuel lines in the tunnel are plastic at the rear and steel at the front. The plastic is shrunk onto barbed ends of the steel lines inside the tunnel. Each line (supply & return) slides out to the rear as a complete unit. The steel portion turns to the right as it exits the forward firewall under the tank.
I think the two steel tubes that you see coming out of the firewall only a couple inches are for heat flapper box control cables.

They turn into steel? I did not know that and it has been driving me CRAZY trying to trace everything. So I guess these steel lines just end somewhere in the tunnel...

Any idea what these lines could be used for? They come out the firewall in seperate locations and point in different directions.

Like I said. I wasn't certain though, from your prior description.
They terminate inside the tunnel just behind the shifter opening.

Those are the guide tubes for the heater control cable.

Ooops, sorry didn't read your whole post. The light went on about the fuel lines and got distracted.

Thank you, it all finally makes now.
