Thanks in advance. 1969 Z....10A build. Which smog tubes would be correct for this? I've identified the pump.
L-R: #1 & #3 are out, #2 & #4 are good.
Very much appreciated. Do you know a reputable person to cosmetically restore the tubes and/or pump?

I have never used them but seen them at our Portland Ore Swap meet.
Do you need the pump Functional or De-Vaned?
Devaned. This will only be for cosmetics.

Once you devain the pump, it you will need to go a little farther with the system. For the tubes you can use 1/4" clevis pins & remove the long tube that goes in the exhaust manifold. The clevis pin goes in the into the tubing. Cut them if you need to. Since the clevis has a flange, it will seat into the exhaust manifold. Next, find a BB that will go into the hose from the carb to the diverter valve. Make sure the BB won't get sucked into the carb. I did this on my 396 when it had 83k miles. It now has 158k with no problems.....Joe
