[DML] Re: are you sure its R12?

["alex morgan" <mauibarber@xxxxxxxxxxx>]

I am fairly confident.  I hooked it up to A/C guages that were for R12.  I 
dont think it would have connected correctly if it wasn't?  Is there any 
other quick way of checking to be 100%?

Quick question. Are you positive your AC system has r12 in it and not
r134a? If it's been filled with 134a then it should have different
fittings installed on the high and low side hookups. If it has had 134a
put in it, then your system is probably working just fine. 134a runs at
higher pressures, and doesn't cool nearly as well as r12.
