Yo,
Nina's '81 244 doesn't have a pressure switch. A/C guy says we have to add one for it to be legal. I think it's a good idea anyway. The dryer has a port where I can add a switch, but I lack the switch. Looks like it's something resembling a 1/8 NPT fitting?
Anyway if you have a used one, I WTB.

You want a binary pressure switch, high/low pressure switch.
I think I paid around $30 for receiver dryer and switch and O rings when I did mine, from Ashdowns

Good practice is to replace dryer when re-gassing. A/C repairer can supply and above gives good indication of cost.
Dryer only is $US19 from FCP Euro.

It is a new dryer, it just doesn't have a pressure switch.
