Any advice on a replacement gauge? Is an "internal syphon" gauge something special?

Just means the pigtail is built in. (and, as the passages are small, more likely to get filled with crud)

If it were me, I'd replace it with a standard gauge and pigtail set up. Use a cross with plugs for the bottom connection instead of an elbow. From the boiler: nipple, cross, nipple, shutoff cock, pigtail , gauge.

Why the cross fitting instead of an elbow, or maybe a T fitting? Does it serve as a cleanout?
