I’m using a serpentine drive and a Sanden compressor. I’ve seen the conversion kits for chucking the York for the Sanden, but can’t seem to find a source for the Sanden lines to interface with the system. Is this a situation where you make your own for the Sanden and R134, or is there a ready made source for them since the Sanden conversion is so popular?
I have the full kit from Classic Auto Air queued up for installation after I get my overheating Borgeson conversion solved. They probably sell the lines you are looking for separate from the kits.
I used modified couplings for use with the original lines. Think I found them on Ebay.
