The entire length of hose is wrapped with some type of fabric tape so I can’t tell what it is.
Maybe a better approach would be to get a hose shop to make an extension hose with flare fittings that’s appropriate for r134a and just add a bit more refrigerant when I recharge?
Speaking of recharging, I saw that autozone has loaner gauges and vacuum pump, I watched a couple YouTube videos and it looks straight forward. Is this something I can attempt myself?
Is it safe to assume all the oil was recovered when Firestone recovered the refrigerant?
Thanks for your help!
