What's in the plastic?

Ok, so I know the lower hose is the heater hose... it even has a prestone cap to simplify identification. Also the hose connected to the VSV I bypassed once I began having a need for heat. Sooo... what's in the black plastic? It's a metal hose of some sort and also comes out of the firewall... is this my fuel line? And if it is the fuel line, how bad is it if the fuel in the line is being heated up before it gets to the intake manifold?

I'm diggin the multi-colored engine bay Krem

So by black plastic, do you mean the black wire loom running along the firewall? Cuz IIRC that should just be your wiring harness...

If that's not what you're talking about, bring the pic up in paint or something and circle the part you're talking about.

yes, I'm referring to the ribbed black plastic tube/wrap.. was actually thinkin fuel line cause it felt like it was metal within the tube covering. Also, I'm hating the multi-color engine bay... but if I ever get the funds together, hopefully I can fix that on the next engine... I don't think I have much longer with the 7mge I have now..

Yes that should just be your wire harness. Goes into the firewall there because the main computer is behind the glove box.

The 20+ year old wiring harness can feel metal-like, but the only way to know for sure that there isn't something else there will be to open up a section of the wrap. You could always tape it back with black electrical tape when you're done
