Orifice tubes

Year: '87
Make:
Model: DeVille
Engine Size: 4.1
Refrigerant Type: 134 conversion
Country of Origin: United States

I did the conversion in '98. Used OEM accumulator/orifice tube then. I intend to replace the accumulator with a new one from ACKits that can use either 12/134. I've got both White GM(.072) and Blue Ford(.067) tubes coming also. The recommendation is to use the Blue tube. Why is the Blue tube better than the White in the system? Thanks for the answer, I appreciate the education.

At 2, I went home with a 10. At 10 I woke up with a 2 !!

Not sure my self as I just add a proper condenser when converting. Chick has had good lot with the blue tube on conversions. Think it keeps the evaporator core flooded at idle a little better.

I can't get them Cads to work on R134a. There are temp sensors in the system that won't work with R134a and when they read a funny temp they turn the whole system off.

Some have changed the diode on the caddies.
