Also disclosed is a gauge configured to display system pressure independent of the user settable shut-off mechanism. A gauge having a rotatable bezel with a needle stop comprising a first needle rotatably coupled to a gauge shaft, and a second needle fixable coupled to the gauge shaft, and a spring disposed between the first and second needles, the spring configured to bias the first needle into the second needle so changes in pressure causes rotation of both is also disclosed.
