I agree Rob.
I have similar setup and found my desiccant dryer and water separator is not needed with proper piping.
I would avoid any horizontal piping near the compressor.
I had one PI that got water inside and lost calibration when it froze. I installed that PI on a vertical nipple and it works perfect. If you are unlucky the PI will get water inside and freeze.
