Must be low on 134 in my system, I've done quite a few R 12's in my years, but never a 134 system, about all I've heard is how critical or how close the maximum weight of the charge needs to be.

My thoughts were pick me up some 134 gauges, let some more 134 out of the system and add some dye for future visible leak detection and fill it up with 134 and run it.

How hard is it to get the right amount of 134 back in the system and how's the best way to tell when you reach that point?

It's fixing to get hot down here so I need to Get-r-done.
