When I switched compressors I knew I did not have any hose leaks so I just kept the old hoses. I ordered 90 and 45 degree fittings thinking I would see what fit the best. I mounted the compressor on its side to give me more clearance for the fittings. That’s fine for a Sanden. I even called them to verify that.
I ended up using the 90 degree fittings with the service ports on them. That gave me the most clearance and best angles so that there was no stress on the fittings or bends in the hoses.
One thing to be aware of, and you may be past this point, the Sanden clutch is a bit thicker than the old York clutch. When I got the compressor mounted my fan was hitting the clutch. Some people move the compressor further towards the fender to get clearance. I was able to add some spacers to the adapter plate to scoot the compressor back towards the valve cover. I got enough clearance to switch to a larger flex blade fan for added air flow. That helped a lot with A/c temps at idle by pulling more air across the condenser...
