The yellow box is highlighting what most trobles me. The metal tube that is about an inch in length is somewhat crimped (it is oval, not round) and the hose that goes to it is cracked at the top where it clamps down. What is this part of the intake, and would it prevent the car from starting?

Also, the redbox highlights another part of my intake that I am worried about. The hose that goes to this is MIA and I am trying to find it, would that also prevent the car from starting?

It is a vacuum line Devin. If that's not plugged in (or the line is cracked / cut) it'll keep the car from idling & running on it's own. It'll start, but won't stay running.

sunny San Juan Bautista,
That intake sure looks sweet! Nice and clean! thumbs_u Yeah, you don't want any leaks in your vacuum lines. When the engine is running you can spray some carb cleaner on the lines where you suspect there could be a leak. If it changes the idle of the engine then you've got a leak there. Don't spray any carb cleaner on that beautiful intake! Use a towel or something to protect it from overspray otherwise the cleaner will eat the paint. If any carb cleaner *does* get on the intake then just wipe it off right away and you'll probably be fine.

The large vacuum line from the rear of the intake is the vacuum supply for all of the vacuum operated accessories from heating, vantilation and air conditioning (HVAC) damper actuators to cruise control actuators. There should be enugh extra length of this hose that you can just cut off the damaged portion and clamp it back on the metal fitting. Before doing that, you may want to unscrew that fitting and verify that it does not have any cracks or vacuuum leaks if has been damaged.

The hose in the red box is, as described before, the vacuum line from the gas fume storing charcoal canister and its purge valve (canister purge valve (CANP)). The valve is located down below the coil pack and you may want to verify that the hose has not deteriorated enough to crack or split. This tap on the throttle body has the full manifold vacuum on it and a damaged hose will definitely cause a vacuum leak and a lean condition. You can plug it temporarily until you locate the CANP valve and ensure that the hose is not a vacuum leak.

So, I assume since this stuff deals with vacuum that the fittings need to be as tight as possible and hoses need to be clamped down well.

Another note, I think the intake was dropped at one point because the vacuum line at the rear of the intake is somewhat damaged. Once my wonderful(sp) room mate hooks his camera up to hios computer I can show the damage. Basically the metal fitting that slips inside the vacuum hose is crunched. If push comes to shove that whole piece can be removed and replaced?

You should be able to find a pipe threaded vacuum line tap at Home Depot, hardware stores or even some auto parts stores. The path through the tap should not be restricted and there should not be any leaks to atmosphere.
