Info on 67 smog hose SB please - original systems

[Ara G.]

Hey guys,
I have a very original L79 67 coupe with a very original SMOG system. I have all original hoses EXCEPT for the short (4-5 inch) hose that goes from the mixture control valve to the carb base. I am researching this a lot. I have seen some hoses with white GM stamped logo with a part number, and some with ribs and NO logo.

Anyone out there with an original system that can give me some insight here? I have a hoard of extra smog parts but don't have one of those darn hoses.

The Chevelle and Camaro 67 smog systems seem to have a ribbed hose coming out the bottom of the valve and a non-ribbed hose with a GM logo coming out the side of the valve (going to the carb - the hose i need).

As always, appreciate any insight.

Ara,
I have the original K19 system that came on my 67 L79. Not sure if the diverter valve is what you are talking about or not. Can provide more photos if needed, assuming this is what you are looking for....

THAT'S IT. The short hose with one clamp on it, can you post some other pics of it? Are there part numbers on it? Length? Is ID 5/8?
Thanks so much....ARA

Ara,
hose measures 3 1/2 inches long and inside diameter is 5/8, outside diameter is 1”. I inspected with magnifier and can find no markings however I have attached a closeup of the ribs. The hose clamp is dated 2/66 as this was a September 66 car which tells me it’s likely the original clamp and hose. It does not appear to have been replaced. Hope this helps.
