I am hoping to add a neutral starting switch to my 56 Dodge 315 V8 and therefore I need to remove the existing power brake vacuum fitting that is threaded into the intake manifold and replace it with a different set up. As a result, after I removed the OE vacuum fittings, I decided to clean them up and document the various sizes, etc. for future reference.
Cleaning involved paint stripper, a 24 hr (plus) bath in Rust Check's "Rust Wash", steel wool and a brass wire brush.
This is where I started:
On the engine:
This the parts after they were removed (with a 1/4" pressure switch for size comparison):
This is how I figured out the thread size of the manifold fitting (with a 3/8" x 2" NPT nipple):
This is what the fittings look like now:
