Tinker, I will take one off your hands but I don't have a clue what they are worth. Let me know what you need including shipping to 46220. Thanks.

I would replace the part with an OEM one. This is one of those parts that you shouldn't skimp on, in my opinion.

Are you sure the insulator is totally missing? You mean the carb is sitting directly on the intake manifold? :confused:
I didn't think that was possible. IIRC when attempting to set the carb directly on the intake manifold, the throttle arm hits the manifold and/or inter-manfold bolts.

I'm guessing that the insulator block is still there, but the heat shield or "wings" that go off the front and back of it are broken off.

Hey, this conversation is pointless without pictures! :flipoff2:

I agree. I've been thinking about how to reply to this one.

There has to be something inbetween your carb and your intake manifold. If there wasn't, then the throttle linkage would not line up correctly. Plus, the air cleaner would sit about 2 inches above the top of the carb. There has to be an insulator there. Like jim said, there might be an absence of wings, but an insulator or spacer exists there.

What about the vacuum port that is inside the spacer?

are the wings needed? I guess that is my main question.

I do have the insulator with the metal pipe coming off of it but my wings are toast.

there is like a heat sheild that spans the intake manifold and then a pretty thin gasket on top of that i will go take a pictue now and post it.
i thought it was normal until i saw a pic of one online and went to myself " that lookl nothing like mine hmmm....."

That's what mine looked like before I replaced it.

I think that the only things that the wings do is insulate the carb and fuel lines from the heat of the manifolds in the hopes of reducing vapor lock. I might be wrong, but that's the only thing that I can think of.

Dosen't do much for a $100 part, does it?

It depends. How long have you been driving your truck without them?

Have you had any problems?

Hedders exist below the intake manifold, so they should not interefere with a full carb insulator.

I don't know about your problem. It might be vapor lock, but I don't know. Wait and someone else will give a definate answer.

so if the wings aren't in the best of shape, at worst, I might be at risk of vapor lock?

if that is the case, I will wait a while on buying that one. I won't be driving it much in the near future.....too many mods on my list.

As far as I can see it, yes. That is all I believe. It does nothing else structurally (sp?) or mechanically.

Someone correct me if I'm wrong.
