It is open at each end. It would have to inflate pretty quick to make a noticeable change and it would then be popping and shooting oil all over. Slowly changing from 0.25 to 0.29 inches would do nothing on the gauge. I am talking something like 0.25 to 6 inches swelling rapidly
The hose would pop before the gauge settles down.
