I have to ask this really stupid question. I am looking to install a boost gauge, and found a nice one but it's only boost, no vac. Most made do both and I am aware that All gas engines draw vac, so this would explain why the majority have both.
So how about it all of you with gauges installed, ever draw a vacuum??
thanks
