I went to a "air condition dude" to fill up my AC,but we find a leak in this pressure regulator.

Can i find this thing on any other vehicle or do i have to buy a new one from Toyota?
What does it do?
Do anyone know how much gas the system contains? It's a Super Saloon with dual AC (cool box in the back).

That thing cost 615au$(3500 swedish crowns) at Toyota in Sweden.

Don't anyone know about the quantity?

Many diff toyotas run that valve, Get a MX 83 one and swap the inside diaphram, I did this with my MS 137 crown.

Ok, Thanks for the answer but there's only one MX83 in Sweden and i don't think that he will offer that thing to me.

I can't find anything like that in my RX80 (just two of those in Sweden)..

if any help, similar (if not ientical) valve is also found in MZ1* Soarers and MA61 Supra - as well as MX73 Cressida. Also Crowns of that era probably have same valve.

There are no Soarer or Cressida (that new) here but there are a lot of MA61 (probably none with AC).
I think i have fixed the leak now.I will pressure test it tomorrow.
