I am not certified, just trying to get by.

In my opinion installing a "self piercing valve" is installing another leak. You state that you have a pump and gauges. No offense but do you know how to use them? Just adding refrigerant doesn't fix the leak, it just adds more refrigerant to leak out. Overcharging the system can do more damage. To properly recharge the leak has to be fixed, the system dried out evacuated properly, a proper charging valve installed (a schrader valve welded into the line,) and then a proper charge with the proper amount of oil for the system. On small self contained systems the amount of charge is critical and a few ounces under it won't cool and few over it will destroy the compressor. It's really not a DIY project in my opinion.
