TY you senor you are a good dude to know!If it is in fact the high side fitting you are having issues with, I found the Four Seasons part number for the smaller 3/16" fitting which is also the Oreilly Murray number. I failed to notice in the previous link those fittings are 12 weeks out if ordered today. My local hub store, luckily 1 mile away from the shop space I lease has them in stock thus I know they are in the Oreilly distribution chain.
