When replacing the top cover with large 0-ring of the Racor (whether you mount
a vacuum gauge on it or not), be sure to not over-tighten it--whether you use
your hand (as Racor recommends IIRC) or a wrench.
I got carried away when I installed a vacuum gauge on the top plate and had
more engine
Make sure you cut open the rubber plug on top of the gauges or their readings
will be way off. Joe. Coquina

I just bought vacuum gauges through Amazon, they are liquid-filled (to reduce
shake from vibration) and are 0- 30 hg. Watch when you're buying them though,
as many are vacuum and pressure gauges combined, and some are pressure only,
and they all show up with you are looking for vacuum gauges.
