small hose from engine room to front on 930

I'm preparing my engine bay since the engine is soon coming back in.

Found a small hose in the right side of engine bay, that looks like a vacuum hose.
Followed this hose over to the left side and went under and went in the torpedo wall heading forward.

Anyone know what this hose is for?
It is not the bigger hose connected to the inlet manifold.

This picture is taken with iphone under the car so not best quality
This is where the hose is connected and goes forward.

Do you have an aftermarket boost gauge in the dash where the clock usually goes? I have a dedicated hose for my VDO boost gauge that runs from the engine compartment, through the tunnel, to the gauge. It might have been used for a manual boost controller at some time as well.

I do not have any aftermarked boost controller.

It is connected to a metal hose in the torpedo wall, so it seems like original porsche connection.

The brake booster line is much bigger and is connected to the inlet manifold.
Will see if I can get a better picture later today.

That looks like the parking brake cable. But it is hard to tell in your pic.

I think right under it is your brake booster hose. It is connected to a metal tube right under the parking brake.

It's hard to tell from the picture.

Thanks guys,
Will blow some air into the hose and see where is goes.

Here is a better picture of the "unknown" hose

Could that be a vent from the fuel tank?
