intake manifold queston

[harleynut]

Question, my 30 Phaeton does not have a vacuum port on the manifold...or any place else that I can see. Is it supposed to?

 

[Drive Shaft Dave]

If it is an early 30 it wont have the vacuum port, being it should have electric wipers.

 

[Mike V. Florida]

The Guidelines say that from Jan to June it had electric and from May to the end it had vacuum. (yes there is an overlap).

Is this Jan-June '30 intake manifold the same as the 1928 manifolds that had no vacuum port, or are there some differences ?

There were at least 7 different manifolds used, four in 1928 alone.

One had the threaded hole with a domed plug, one had no hole, one had tapered "feet", and one with no hole but a bulge.

1929 the hole showed up again with an oval plug.

June - Aug 1929 had the boss but not drilled.

Mid 30 the hole was moved.

Details are in the Guidelines
