As I was cleaning up the engine bay I starting looking at the fuel lines and found this. Any ideas on a fix without having to replace the center tunnel lines?
It's the line that comes out of the firewall on the left.

Replacing those lines in the tunnel is actually very easy--Just remove your shifter-and the other access plates so you can get your hand in there-and your splash pan on the front crossmember---and feed in a new section of metal line---
This is a good thing to do anyways--that plastic line that has been in there for the last 30+ years is ripe for replacement anyways--

the xxxx thing is a spoiler for air flow, it turbulates the air under the car so it hits the heads, instead of just flowing under the car. i have read that it keeps temps down another 10 degrees or so.
there is now way it affects the fan for rocks and stuff, the fan gets its air from the top. sorry
i have a set if someboby needs em for some reason a water cooled suby does not need them

I doubt that it will be all that difficult to do. Just want to get as much info as I can before starting. I guess I'm lucky with this one because my son is an instrumentation tech so bending and fitting tubing is his bag.

Mc Master Carr industrial supply shipped me some Nylon 11 tubing, which is great for the fuel system. Nylon 11 is flexible, and gasoline resistant. I think the original is a Nylon, it will last a long time, however it is readily attacked by sulfuric acid (battery acid)
They offer both metric, and inch tubing at about 40 or 50 cents a foot Althought the 8 mm is the exact fit, I choose the 5/16 inch (extremely close size, not really noticable, and besides, thats what my rubber fuel hoses are, 5/16 inch) I choose this, cause the metric size only came in colors, including white, the inch size came in a natural non-pigmented nylon color (transluscent white) It is listed as drinking water grade, as it has no pigments to leach out, the colored ones would hide any dirt that you otherwise might detect in the translucent line, and I think the natural nylon likely is more like what the factory line might have looked like when new.
I am not doing the tunnel lines, as they seem fine, but the ones from the firewall out are getting re-done in new Nylon 11
Hey, in the photo, is that a standard cloth braided Low pressure fuel hose I see? If that is low pressure, it cannot be used on the return line, only the supply line up to the pump, If you have a front mounted pump all lines back from the pump MUST be high pressure Fuel Injection grade hose.
Only the supply to the pump is at low pressure, however, it is pretty well accepted those cloth braided lines tend to be cheap, and rot fast, so use all the good stuff high pressure FI hose thru out you car. I even do so on my low pressure carbed Spitfire and Bug, The FI hose lasts much longer. The regular hose is unsafe on a FI equiped car, do not use it in that application.
