Engine Setup and Vacuum Lines

[ukkid35]

‘Block off purge line’ – which line is that on a 4.5?

Is it the vacuum line that goes from the four way junction above the ac compressor to the bulkhead?

Also where does the other vacuum line go from the four way junction (other than the two that go to the inlet manifolds)?

TIA

2 to the manifolds, 1 to the rear to the carbon canister purge valve, 1 to the front to the small take off on the catch can on the underside of the drivers side air box.

Thanks, that would explain why the rear line has a break/union in it - to allow it to be blocked easily for Engine Setup.

I got a little confused when looking too as the manual shows the 4.2 and isn't very clear.
