Question 300TD Wagon

I am new to this site and would greaty entertain the idea of help on the 300 TD wagon. The car can only be shut off manually under the hood, which leads me to the area of vacuum. So I pulled off one of the lines and blew into it I heard what appeard to be air bleeding off somewhere in the area of the Vac/pump. There is a tree also in that area but it seems to be sealed. could I be feeding back pressure into the pump? And, where is the supply comming from? Thanks in advance.

basic tests for vacum shut off.

1) start it and apply vacum to the shut off, 12 to 15 inchs should kill it, if nit, shut it down and see if it will hold a vacum, if not, replace the element.

2) check the vacum to the shut off element by putting a guage on the line leading to the shut off (as in bypass the shut off) and turning the key to off, it should have 14-17 inchs to the shut off. if not, tap in firther upstrem and check for other leaks. (door locks, dash elements, various devices under the hood.

I've replaced a bunch of the shut offs and a bunch of door lock actuators for leaks causing these not to shut off.
