Throttle body intake boot and pipe that comes off it

[captainsossige]

Hi All,

I'm replacing my intake boot/elbow as it has some cracks.

There's also 2 pipes that come off it that I can't find on realoem or anywhere.. One goes to the inlet manifold (vac system), which is OK and in good condition

The one i'm looking for comes away from the engine and up and over towards the right hand side of the engine bay and seems to go down to the bottom of the engine..

Any ideas what this pipe is called or it's part number? Can I just use a length of standard hose from a factors?

Any help would be much appreciated.
