John;
I made one of these last summer for less than $5.00. I used copper tubing
from a hardware store. As for the connection to the exhaust manifold I used
copper plumbing fittings, also from the hardware store. I did not find the
proper thread size for the fitting (although I am told they do exist)
because I was in a hurry. So I retapped the threads on the manifold so as
to accept a standard plumbing fitting.
My new air pipe seems to work great. Hasn't rusted and it doesn't get as
hot as the hot water pipe from our water heater.

Subject: Smog pipe
Got a question for you all. I have a 77 1500 Spit. with all the smog
stuff on it. I have a new smog pump, but the metal tube that goes from
the smog pump via the check valve to the exhaust manifold is shot. I've
looked in TRF and VB cats. and neigher lists the tube. So I went out today
to try and have one made.
The company said they could make it, but, the needed to know how the tube
was held into the manifold. I mentioned that I though maybe a ferrel, but
the clerk at the shop said he didn't think so, that the end of the fitting
that screws into the manifold didn't look like it was designed for a ferrel.
So I guess my questions are:
1. How is the tube held inplace at the manifold end?
2. If it is held in place with a ferrel, is it simply a copper or steel
ferrel?
3. Anybody found a source for the fitting that screws into the manifold? It
is a very fine thread, and the tubing shop said they didn't have anything
like that.
In case anyone is interested, I looked up tubing bending in the yellow pages
to find this company. They said, that they could make the pipe up for about
$40, give or take.
TIA
John
