I tried a couple of different locations before finding a "stable" one. The first ones I tried gave a big jump as whatever was being supplied vacuum by that line turned on or off.
I tap into the fuel regulator vacuum line now.
I get around 18 in.Hg at idle in my 1.8 litre Mazda.
Every car I've used a vacuum gauge on has given different readings.
