If you already bought a gauge with the bleed fitting, then all you need to do is visit a Grainger to get a quality replacement gauge. You could also get a glycerin filled gauge. But it requires more time to deal with, as the ambient temperature affects it. It requires you to open a vent to equalize the pressure on the bourdon tube. The advantage to the glycerine is durability. You can get a large diameter segmented gauge too.
