Sometimes I have to be told twice. It's a bypass valve, ok. Just one more thing please.
What is the part listed as 9F491, and where does the bottom hose lead to?
9B289 is the air bypass valve. 9F491 is the exhaust air supply valve (I told you this in post 12).
The 9G459 hose that leads from the bottom of this valve, routes to the 9A487 check valve that's made as part of the pipe that goes to the rear of the engine.
The short 9324 hose that leads from the side of this valve routes to the other 9A487 check valve that threads onto the 9B449 exhaust air supply manifold.
I wouldn't be surprised if one or both of these check valves are missing.

Here's the pic again.
This reminds me of the time a pal of mine bought an '83 Cougar with a swapped 302 from a 1984, ALL the emission parts were missing. What a PITA that was finding all the parts and this was in 1986!
Where about in The City do you live? My niece lives in Pacific Heights.
In the 1960's, my aunt lived on Taylor Street, just down the hill from the Pacific Union Club (former James Flood mansion) next door to the House of the Flag.
I live east of twin peaks, almost the middle of the city. Some call it dolores heights. To me it's baja noe.I'm surrounded by three hills and live at the bottom. this place has changed so many ways. I have managed to hang on to the house, but all my neighbors are new. I like the weather. The taylor you mentioned is meat the theater district. Your niece is in a good place. FAST moving and real smart It's a boomtown every decade. It's not just bankers and finance Any more. Every body seems to be new or a tourist.
Did you know that the slot machine was invented by a man that lived near Mission Dolores? They also made and sold pianos. I have one (upright): R. Fey & Co. San Francisco.
The first key has a penciled notation on its side: May 1, 1879. It has 85 keys and came from a former "house of ill repute."
When I took it apart to rebuild it, found dozens of 19th century silver coins.
R. Fey rings a bell. I looked up info about people that used to live here at the turn off the century. There are tons and tons of last names,...old sounding names that you don't hear about these days. Yeah, and one thing we did as kids here was collect old coins. You Could find some old coins back in the 60's.
I found both parts, but I'm wondering about your remark in post 16B289 is the air bypass valve. 9F491 is the exhaust air supply valve (I told you this in post 12).
The 9G459 hose that leads from the bottom of this valve, routes to the 9A487 check valve that's made as part of the pipe that goes to the rear of the engine.
The short 9324 hose that leads from the side of this valve routes to the other 9A487 check valve that threads onto the 9B449 exhaust air supply manifold.
Per my drawing, there's one pipe after the check valve that goes into the back of the engine, just beneath the rocker covers. It splits into two so that it goes into each side of this 140 horsepower (Wow, ha ha) engine. I must be off my rocker, now.
and then, there's the small hoses at the tip of the exhaust air supply and the airbypass valve. Where do they go? Thanks very much if you can help.
So now the question would be transformed to where/how does the smog pump reach the catalytic converter, I guess. I understand that air is pumped into the exhaust (as like where the other branch of the hose goes) to finish the consumption of the gas, and to also prevent a backfire before it reaches the Catalytic converter. Here's hoping there's an answer.

Look at the pic, the check valve is shown before the #2 pipe that leads to the converter. Pic related to 1985 Continental 4 door sedan (DC) and Mark VII (K).
There are two of these pipes, but only one has the check valve.
