Why do you need one that measures to +/- 7?

Our trucks are restricted if the vacuum at the valve is over 5. Normal is 2.5 to 3?

When you run a lift pump you will have positive pressure at the valve...Fass and Air Dog 8-10 psi depends on pump model...

Yep JOHN from Kennedy said they have a 15 psi gauge and 150.00 is probably a good deal from what I have seen so far...250 for Kent Moore gauge...went to a couple stores Parker ect. to see if we could figure out valve..must be a Japanese type connection..Can anyone tell me if valve unscrews from stem and what type of thread..?
