Hello from France,

On my 400 engine, I have a problem because some vacuum lines are not connected and I don't know how to connect them.

for example, the canister has a vacuum tube to the fuel tank, but the other vacuum to the engine is not connected, I have two other vacuum lines not connected on the engine :censored:

I found one picture on internet but no clear diagram.

Does anyone has a vacuum diagram for the 400 engine ?

Thanks :)

Finally I found a complete vacuum line diagram for 1979 ford 400 engine but it doesn't help.

If you have a MARK V 400ci could you help me to identify the vacuum line not connected on my car that are on the pictures ? I want to know where they are connected on your engine because my carburetor is not the original one then some vacuum lines have not been connected by a previous owner 😟
