Does anyone know? I can't figure what it connects too. It has never been connected for the 30 years I've owned this car. Also what color is the wiper override switch in the pic supposed to be painted?

It's a 69 L71 engine *NM*

Re: What is this line in the engine compartment?
I believe that is the vacumn source line going to your Heat/A/C vacumn switch in your center console.Comment

Do you know where it hooks in the engine compartme
It has a clamp on it.Comment

Re: Do you know where it hooks in the engine compa
Been awhile since I had a Shark. Looks like the hose that goes to the heater hose water control valve. Maybe your car has one, maybe not. Some people took them off when they started to leak. The valve shuts off or modulates the flow of hot water to the heater core.Comment

Re: What is this line in the engine compartment?
I have a '69 L-46 no AC. This line runs to a "T" that connects to the port(near the right side fender "gills") that sends vacuum to the wiper door "Motor". The clamp you talk about keeps the line from pulling off of the "T.
hope this helpsComment

Can you explain a little more?
Okay so it goes to a tee on the wiper door actuator correct? That is a large hose. Are we talking about the one in the front of the actuator or the back. And where exactly is the tee connected..at actuactor itself? mine is missing a tee there... can anyone send me a picture please....PLEASE...thanksComment

Re: Can you explain a little more?
On my 69 there is a hose with a "T" in line with it. The T part goes to the small hose you talk about. The other end is in line with a larger dia. hose with a faded yellow stripe. This line goes to the center port of the vacuum relay that supplies vacuum to the wiper door motor. The hoses that connect to the front and back of the canister come from the same relay very close to the fender gills on the right side of the engine compartment. So find the relay valve, then trace the center hose(yellow stripe) and it should go to a "T" just in back of the ignition shielding, that is if it has not been removed.Comment

Agree with Mike. It is the vacuum hose that feeds the HVAC controls inside the car.Dick WhittingtonComment

Re: What is this line in the engine compartment?
What you need is the 69 AIM...If it's like the 70 AIM, UPC 12 has a page somewhere around A15 that shows the routing of all the vacuum tubing on the firewall. Look for a painted stripe (red, white, no stripe, etc.) on the tubing...that will help someone with an AIM figure it out for you.
The only vaccum tube(s) penetrating the firewall are vaccum supply to the heater controls, vac return to the heater hot water valve, vac supply to the instrument panel vaccum harness (headlight door controls, etc.), and vac supply to the wiper door override. On your 69 non-air car, some of those may branch off a common line behind the dash. The vacuum supply to the heater control or to the heater water valve is likely to be on the right hand side of the firewall like that one.Comment

Okay I think I found the connection but!
Someone bubbad my car because the hose you are talking about with the yellow stripe has been taped together and there is no tee...my question now is on that hose there is only about a 3 inch vac line then it is taped together but there is no way the small hose I'm talking about could ever reach over there. Where does that yellow hose go? Mine goes directly to the vac tank and I can't find the pic of the lines in the Aim.

Re: Okay I think I found the connection but!
I can't tell what the focus of your picture is anymore, but if you're talking about the striped hose from the check valve to the firewall, that one should go to the instrument panel vacuum harness (headlight switch, headlight door manual open, wiper door).
On a 70, I THINK (trying to reconstruct my own vacuum system) that tube going into the firewall tees coming off the check valve, and the branch tube goes to the heater controller. I expect "Bubba" discarded the tee and just connected the check valve directly into the instrument harness tube so his headlights and wipers would work...must have lived in a wet, warm climate.
The second tube off the check valve should go to the vacuum reservoir. The large connection on the back of the check valve is your main vacuum supply from the intake manifold. There should be a filter between the manifold connection and the check valve.Comment

Re: Okay I think I found the connection but!
My AIM is unreadable, so I took a flashlight and traced the hose with the yellow stripe. It starts at the vacuum storage tank, then goes to a 'T' just behind the "dog box". The center of the T goes to the small hose that is not connected on yours. The other end of the T goes to the center port of the vacuum relay that operates the wiper door. See if all the hoses are connected to this relay(near the right fender gills). I have no idea where the small dia. hose goes once it disappears into the bulkhead. I agree that someone made a quick and dirty repair in this area. I would also think that if there is a vacuum leak in this part of the system, your 3-2s would not like it.Comment
