The lower vac. port of the throttle body of a 1980-1983 US model engine should give you only vac at idle, you should check that, as its the common port for the distributor retard at idle in case your engine is a 930.16/07 one.
The manifold vacuum given at all revs is the correct one you need for the WUR vac. mechanism. Its the lower port behind the throttle body (green hose). (The upper (blue hose) one is for the distributor advance.)
Below you can see where normally those manifold vac. hoses (green) lead to:
As of your signature :-) I guess you dont need the deacc. valve and the cruise control, right?
If not already done just unplug the hose leading to the T-Part from the port of the throttle body and use a new hose leading to the WUR.
Cause by this as a needed side effect the vac. connection to the deacc. valve is removed an when deaccelerating from high revs the deacc. valve wont open and so the vac wont fall that low that the WUR will enrichen the mixture :-)
This is also very important for you
mikesarge if your engine comes with a deacc. valve
