Replacement Choke Tubes
#1
#2
I've made them from steel brake line. As I recall the parts catalog says to make from bulk material. I'll double check that.
There are two lines. The cold side goes from the exhaust manifold to the air horn of the carb. In the picture the nipple with the vacuum cap is where it connects to. The hot side goes from the exhaust manifold to the threaded fitting on the choke that kinda points down.
The hot side has an insulating sleeve that goes over it.

I checked the parts catalog and it shows the outlet tube is D4OZ-9819-A. The inlet tube has the notation "make from bulk tubing". The outlet tube also uses an insulating sleeve part number 381490-S145A.
I checked both part numbers and no dealer or obsolete parts supplier has either.
This is roughly what the setup should look like.

I did some digging. Mustangs Unlimited has reproduction lines for 302 2bbl Mustangs and Cougars. I don't know for sure if they'll fit a truck or not.
Plain steel is $21.95 and stainless is $29.95

The chamber itself has a filter in it that resembles steel wool. The bottom of the chamber has a fitting that is pressed on to seal the chamber. In the side of this fitting is another hole that the cold side line goes in.
It all just presses together, nothing fancy.
If the old lines are broken off in the manifold, it's very easy to just drill out the broken pieces.
The filter and fitting are also reproduced and most Mustang parts dealers carry them.
Here's the filter and fitting.
