Greetings Drivers,

Working on the engine of my F73, I come across this vacuum line coming from the alternator vacuum pump but not plugged anywhere on the other side!
The vacuum pump has 3 lines, 1 to the brake servo, 1 to a vacuum distributor (splitting and routing vacuum to the transfer case) and 1 going to the back of the engine, behind the turbo, that's left open!

Below are pictures where you can see it.

Any idea where it goes and where it should be attached?

Help is appreciated.

Thanks.

Regards
