3.2l intake vaccum line ID

[sleepdoc]

Hi All,

I stole this pic of a 3.3l intake system from another post.

Please help me with some identification.

1 What is this copper line and fitting to the manifold for?

2 What is this little vacum nipple for.
I see the line to the fuel damper and regulator,
and the one to the ambient air valve.

3 What hooks to this big nipple on the intake boot?

thanks Mark

Thanks Jim,

Why is it connected to the manifold and the intake boot. If it is to supply vacum to the booster can why the double connect?

These pictures should help you sort things out:

Thanks Kurt,

I do almost have it. The problem is my engine is in a 914/6 conversion that I bought half done, so I don't know where the other end of some of those lines go. I know now to block off the brake line as I have no booster can. Also I live in Hawaii and the ambient air valve is missing, so I will block that one off. I get the loop between throttle body and thermo valve, and the thermo valve y out to the fuel damper and reg.

Where do those big lines go?

The bigger of the two hoses is just a breather hose for the oil tank. The smaller of the two hoses eventually gets routed to the charcoal canister.

Thanks thanks thanks Kurt,

I now have enough info to make it all happen.
