Thread: Dorman Intake question

Hello all,

I have ordered and received the Dorman intake manifold that I plan to replace on my 02 GP N/A. It looks pretty complete with all necessary gaskets, o-rings, etc. but I have a question. In the middle of the gasket assembly, there is a plastic tube (about 1/4" dia.) that is about 9 inches long and has a 90 degree bend on one end. It is not connected to anything, but is held in place by 2 plastic clips in the middle of the plastic webbing of the gasket assembly. I have not removed my old intake yet, but I just can't figure out what this tube would be for. Does anyone know what it is for and, do I need it?

Thanks to all for your replies. I just thought I'd add a note to those who are looking for a UIM. I bought the Dorman replacement manifold (#615-180) and even though I have not yet installed it (waiting for warmer weather without 30" of snow on the ground), it seems to be very complete. All gaskets, O rings, pcv valve, MAP sensor cage, vacuum take-off, etc. And, I bought it at Amazon for the measly price of $58.00. And, free shipping, no sales tax. This is the cheapest price I have seen anywhere. I couldn't believe the price since the gasket set alone elsewhere is $42.00 without anything else. Don't know how they are selling it at that price, but who cares.... Autozone has the same item for $130.00.
Now all I have to do is gather the rest of the parts I need to do the LIM and valve cover gaskets....
Thanks again.
