  I wouldn't  convert, but that's just me.

  If you are going to, I'd replace the drier and expansion valve.  While in the process run a gallon or so of flush through the system and then re-fill with the correct oil.  Don't forget to R&R the compressor and flush/refill it as well!

  Do not use the port on the compressor.

          Well back to business. The r12 leaked out and I've located and repaired the leak, but I want to install an enviro friendly gas. Any tricks to converting to 134a, I've installed new valve cores and new fittings.That's it. I bought the interdynamics conversion kit. There are three ports to hook up to. One on the compressor (low side), one on condensor (high side)and one on a tube with two fuel hoses going to fuel distributor (?). Which ones do I use? Thank's, Peter
