I'm doing the trans cooler and water separator part of this install and if it isn't enough, I'll add the copper on the wall. About $100 for the cooler and filter, plus a little soft copper tube and fittings.
I just made this mod to my compressor but without the wall piping. What a difference! Air going into trans cooler is about 160* and air coming out is about 85* water separator takes care of almost all the water at that point. Thanks for the info!
