I need to do a little troubleshooting on my a/c. It's still got R12 in it, so the two Schraeder valves are stock. At least I think they are - my hard lines that run across the top of the radiator were replaced back in the late 90's, I think with an OEM hose set.
The high pressure port on the hard lines is smaller than the low pressure port on the drier. I have an R134 gauge set, which seems to fit the low pressure port, but not the high pressure. Went to friends house, he has an ancient R12 gauge set, and his gauges fit the low pressure port but not the high pressure. So I am momentarily stuck!
Thinking my best option is to find a high pressure hose that will fit my gauge set on one end and fit my high pressure port on the other end. Or, if that isn't feasible, just buy a new R12 gauge set that will fit up ok. But I am worried about just ordering a cheap gauge set - since my friend's set did not fit, how do I know that a brand new gauge set will fit? The internet searching I have done has turned up some fairly inexpensive gauges sets, but they never specify the fitting sizes. So can someone educate me here? Anyone know where I can get the proper hose, or the proper gauge set, or something?
Thanks
John
