Guest whitey Posted September 6, 2014 Share Posted September 6, 2014 I have a 1988 Reatta. I want to hook up my A/C gage manifold, low and high sides. The low side on the dryer/accumulator is straight forward but the high side has a smaller fitting, too small for my hoses. This is the original R-12 system. The high side fitting I'm seeing is up near the firewall, drivers side. Am I in the wrong place or do I need an adapter to convert this smaller Schrader valve to the standard hose connector? Also, any idea what is this valve size for future reference in case I need to replace a leaky Schrader there. Link to comment Share on other sites More sharing options...
