Review: Great for mechanical or automotive use - This is a great water filled gage and doesnt give erratic readings in rugged conditions. I used one to monitor my brake vacuum in my 69 Grand Prix after installing an electric vacuum pump and canister to augment my braking system following a rear disc brake upgrade.
Review: It does exactly what I need it to do. - The bushings included came in handy and worked perfectly. The gauge shows 21.5 inches HG at 7250’ elevation. Maximum achievable vacuum at this elevation is 23.1 inches HG. I would say that is pretty accurate using a small vacuum chamber. The gauge is just reflecting the capability of my vacuum pump. It arrived with 5 inches HG as a result of pressure differential from California. I simply had to lift the small black plug on top slightly to allow it to equalize. DO NOT cut the tip of the plug. If you do, the glycerin will leak out of the gauge. This gauge is a bit larger than my old one and easier to read. I don’t really need to know the exact inches of HG for my application. I only need to know that I have a good seal in my chamber. This gauge does that very well. I would buy this again.
