cap tubes are why I figure they invented whiskey.....
OK I replaced cap tube and drier and triple evac to 490 microns and all seem ok and i will be stopping by in am to give a quick looksee. thank you Guys,.
80 Psi high side cut out old drier.
Did you cut or torch old filter. Is that 80 on the high side?
What took out the first compressor? That powder is a result of a reaction in the system (contaminants) and neither a strainer or filter will trap it. you most likely will need to replace the entire system with virgin components, or consider a TXV conversion, as its less prone to this type of restriction. Or it might be more economic, to replace the case. good luck. this write-up by supco is pretty good,, http://www.supco.com/images/pdfs/Man...g%20Manual.pdf
