Hi all.
For a 2000 Discovery, the cruise control vacuum pump assembly has 2 ports facing spark plug 4 aiming downwards, one about 1/4" and another 1/8" with a 'T'
The 'T' has a branch with no hose. Where is it supposed to connect, or is there a hose diagram for that assembly ? Did not find it at the shop manual.
Thanks.

 

The whites one does not connect to a hose, it is a dump port, the BCU decides to shut down the unit and a valve opens to remove all vaccum, sucking air in that spot I suppose.

 

Thanks for your always great assistance, Savannah Buzz. The larger white one I have it connected to the vacuum actuator, the small black one has nothing plugged as in the picture attached above.
Will leave it as is and try.
