my 96 RMW failed smog in California due to "Rotted" evap hoses. And a vacuum nipple that was not broken on Sunday, but was broken after the inspection.  
I am not seeing any hoses that show sign of rot.  All that i can see are pliable and showing no cracks at the connections or where there is a clamp. I have seen really rotted vacuum hoses when got my 54 Chevy back in 1993.  

Does anyone have a diagram of the evap system and where everything is located? the top of the engine hoses look good expect for the part they broke, however the hose going to it looks good.

The hose going into the nipple.
Good examples of the hoses. They may have some dust and dirt on them but soft and pliable.

Timely topic, just so happens I've been replacing the wheel well extension on my 94 Caddy Fleetwood. If we're talking about the same thing, the hoses that go into the charcoal caster, passenger side. They are definitely rotted. They are 26 years old. I have got the canister out with hoses attached, if that's what you need info on, I can take a picture of it.

Thank you, i did not see the hoses that go to the evap canaster, nor where it is. Now i do. Should be an easier fix now.

What can be used to replace, what i think is the bleeder valve between the 2 hoses?

I was able to purchase the secondary air pump hose with the bleed valve from a Chevy dealer in Northern California. They had 1.
