Re: 1947 clipper vacuum choke pull-off

If the manifold is drilled completely thru both sides, then a piece of steel tubing should be inserted and swedged at both ends to form a seal, and the choke vacuum line inserted part way into that so that it can pick up the heat w/o picking up exhaust gases. Very typical arrangement right up thru the last Packard V8s and most other cars of the era. The amount of vacuum that the automatic choke draws is miniscule, assuming it hasn't been buggered.
