25 is the cover I pictured on the other page... and pretty much right where the number is pointing I think is the location of the expansion valve. But don't quote me on that.

Hello,

I have a 88 GT and I am working on my AC system. Got everything done, but where is the orifice tube located?
From the manual it looks like it is on the engine side of the passenger footwell, but the two AC tubes are empty.

Any hints?

Thank you

Found it, right tube wrong end.
It is right next to the coolant container.
My garage is filled with embarassment.
