Yeah, I'm doing this and I'm going to get a hose made adding a high side cutoff switch as well. > I'd also replace the orfice tube with > one calibrated for R-134a, and if you live where summers reach 100F, > upgrade the condenser as well, especially with any vehicle having a > large passenger compartment. I might try out one of those "smart" variable orifice valves. 20 bucks or so. > The Ford FS10 compressor isn't a good > candidate for R-134a, and Ford switched to another model (FX-12 or > FX-15 was the model) when they started installing R-134a at the > factory.
