OK I am in the process of vacuuming and servicing my 134 AC on my EK as per the writeup in the FAQ.....My question is, how do I connect the can to the yellow line on the gauge set. When I was at autozone the only Tap line they had said R12 on it. Also, that is what was used in the writeup but I have a 134 system and the only lines I see for the can are the quick disconnect type (which would require me to disconnect the gauge and service it straight on the condesnor fitting) Any suggestions???

 

You need a small brass adapter, you may get one from an autoparts store, but definately from an A/C supply house.
Or just connect your 134 charging hose/can directly to the service port to charge, then pressure test by swapping gauges, don't forget to bleed the lines of the gauge set or you will pul unwanted air into the system.
