Hi ho Steve O', yep I'd have to agree with ya on this first part. You can send the gauge out to have it resealed and recharged. That will only cost you around $125 to $150. Or, you can spend a third that much just buy a reproduction one from one of the vendors.
As far as repairing it your self, good luck. I'm a pretty dedicated, or some would say bull headed guy, and I spent a couple hundred hours researching the possibility of repairing them at home and was unsuccessful.
Basically you have to chill the bulb enough to liquefy the gas than keep it cold while you swap the capillary tubes. Not an easy task to say the least while your applying heat to solder the joint. And then if you’re successful and didn’t have a leak and didn’t vaporize the ether there is the calibration part of it.
Save your self a bunch of money and time and just buy a repro and have done with it.
