I think it's ok. There is vacuum, so the pipes are ok. There's just no suction as I would have expected (a lot of the other vacuum pipes on the car suck quite hard).
I've now tested the auxilliary air valve by pinching the pipe going to it whilst at normal operating temperture (as stated in the Haynes manual). As the revs do not go down it looks like this might be the problem.
I would have thought the pipe should be pinched when cold ?? Perhaps the Haynes manual is wrong ?

If you don't have vacumn to the regulators it pumps your engine full of gas an bad idle rich condition. You will just have to trace the vacumn line and find the place it is loose. Not easy on a 951 due to all the plumbing but on a na 944 its right behind the thottle body on the side, easy to find, little tiny vac hose.
