Where does this vacuum line go to?

#2
On my car the big pipe (no 1 in the diagram) looks like the cross pipe between the two manifolds. It runs across the rear of the engine. The spigot is a take off for a manifold vacuum signal to the ECU in the boot. If your car has a similar setup as mine, this spigot connects to a vacuum tube that runs under the car and ends up at the ECU.

Not nessessarily, the hard line pipe is pretty well hidden up in the transmission tunnel.
It's not a bad idea to disconnect both ends and give it a blow through and then to block off one end and check for leakage before hooking back up.

The problem is that it is impossible to connect the flexible from the crosspipe to the hard pipe with the gearbox in place. When I replaced my engine after my rebuild, the flexible got misaligned and was outboard of the cam covers. It was impossible to get it into the centre of the engine V with the engine in place, I had to pull out the engine a bit to just get the pipe into the centre of the V. So if your flexible is disconnected and not there to reconnect, it would be worth trying to loosen the front engine mount nuts, then undo the gearbox tail and CAREFULLY lower the tai a bitl, thus with luck, freeing up just enough space to connect a rubber flexible (A fairly solidly walled one that will withstand the vac).

Is yours disconnected? If so you have a real pain ahead. When the crosspipe is in place the spigot should face downwards and backwards from the cross pipe. It connects via a short rubber flexible pipe to the steel pipe SC6 mentioned. The hard pipe runs up the LHS (US driver's side) of the gearbox tunnel (NOT to be confused with the fuel return pipe or the battery main feed cable to the firewall posts) and further back it is in the propshaft tunnel.

Thankfully, it is connected. I wanted to renew it, but it seems good to leave well enough alone.
