Does anyone have a photo of the air dryer supply line port in the engine compartment on an early 80's 9?
Here's a pic of the compressor discharge line connecting to the oil separator then on to the air dryer up front. Is this what you need?
I don't think it's ideal to have a bend in the discharge line like mine. On my list to change out.
You could just support it so it remains on a horizontal plane. Definitely asking for issues if you were to go into sub zero temps with the a collection point in the line like that.
