help with identification

Year: 1991
Make: ford
Model: f150
Engine Size: 5.0
Refrigerant Type: r12 orig
Country of Origin: United States

I am helping a friend out that bought a pickup and was getting ready to replace the accumulator (system was empty) and compressor. Went to remove the orifice tube and there isn't one. This truck has factory installed AC.

please refer to the picture - isn't the tube on the right where it should be? That tube was connected with a spring lock connector that you can see hanging down to the right.

Yep, that's where it is supposed to be.

use a piece of wire to probe down the lower tube, (I use a short piece of welding rod) but not long enough to enter the evap, don't want to damage anything... see if it stops half way down. Sometimes the O tube can be blown into the evap, but should stop before going around the bend..Let us know what you find...You should also see three crimps in that line that holds the O tube in place....

Thank you. Will do. I will report back with my findings.

This system used to be r12 what weight pag oil should I use for 134?

Use PAG only if the system is flushed clean, other wise use a good ester like BVA auto 100 If using PAG use 46 viscosity double end capped..Hope this helps.
