Re: 134a what size orifice
It is what I used when i swapped from 12 to 134. I only went white fixed because I had it on the shelf and that is what is called for.
I am using a Sanden SD7,, With the fixed i could not get decent temps.. My motor runs around 2,000 or less in town. Chris |

That's just fine for hydrocarbon R290 and R12. You need a slightly smaller orifice for R134a and HFC152. As I said the Ford blue is 0.067 and it seems to do the job.
