Jay, OK, 15" of vacuum at idle! Your Westy is now King/Queen of manifold vacuum until someone can top that. How many miles on your engine? Original valve guides? This is in line with the result of my experiment that I posted last Thurs/Friday: in order for the fuel pressure regulator to give 28 psi at the fuel line test tee you need 15" manifold vacuum (1.9L engine). I connected my gauge to the same place you did when measuring vacuum. Connecting the gauge to other locations didn't affect my measurements.
