A/C Machine Conversion
I came across an old Robinair R12 A/C recovery, recycling, recharging machine. The machine is compatible with R134A freon that I would use it for. My question is, can I flush the R12 recovery tank and use it for R134A or are the tanks totally different?

How is that done? Does the tank need to be modified? I've heard of the idea before but never saw how it's done.
