EDC mounting water/oil seperator

I got my AC compressor hooked up and ready to go other than threading the ports. Totally juiced.
The setup that was on my truck allowed alot of moisture to get into the lines and I think thats what lead to the demise of one of my valves.

So I was just thinking with my water/oil seperator, should I mount it right after the compressor in the engine bay, or should I mount it at the tank instead?

i believe that it is better to mount at the tank. right near the compresor the air is hot and the water is just vapor.

That was kinda my thought. plus it gets hot running near the exhaust underneath too.

im mounting mine by the tank
