Are these hoses connected correctly?

[torbsim]

Hi everyone, I would like to draw on your expertise once again.

The previous owner used the hoses with the following connections, but I would like to make sure that these are correct, as I have already experienced a lot when refurbishing the Mustang. Please help me briefly if the connections are correct:

First:




Is orange correct from the metal to the blue emisson canister? I assume that it is the exhaust gas recirculation?

Nothing was currently connected to red, so that can't be correct. Which connection is missing there and where does it go?

Second:




Then there is green which is connected to the valve and goes to the black a/c vacuum canister. is that correct?

Thanks for your support
Ben

The orange is correct. It is for recovering fuel vapor from the gas tank. Fuel vapor is pushed into the blue canister generally while the car is off and the gas tank heats up while sitting on hot pavement or generally heats up on a warm day. There should also be a paper tube that also connects to the blue canister and the air cleaner that sucks the fuel vaper into the air cleaner while the engine is running.

The red connects to an intake manifold vacuum port to help the automatic transmission shift gears.

The green is also correct. It is a vacuum connection for the heater/ AC system black canister that provides vacuum to the various vacuum actuated items in that system. One of those being the valve in the heater hose in your pictures

Below are some file links to my Google Drive that will help you determine what vacuum line goes where. From your photos I could not tell the year Mustang you have, so the info I have provided is for 1973. If you have a 1973 year model Mustang, the 1973 Emission Control related documentation is from Volume 6 of the 1973 Shop Manual. You will find a section on the Fuel Vapor Control system, as well as the vacuum schematics for 1973 engines. The 71-72 emission control systems are very similar to 1973. Below are is also a link to some YouTube videos I did on the routing of the fuel evaporative lines for the Fuel Vapor Control system.

If you have a 71 or 72 Mustang, the following link is for = a PDF file for all vacuum schematics from 1968 - 1972.
