I can blow through my drain too in all positions (order just got here)! Will the drain act differently under air pressure?

Air Flow goes in to filter and goes out. The drain is for water trap. You can manually turn on/off. Try to turn off and see if that stop the air blow through drain.

How often does the filter need to be replaced, and does this come with any air hose connectors (male/female quick connects)?

It truly depends on how much you use the item, as far as filter replacement. And no this does not come with quick connects. Usually this filter is put in line with tubing or some other sort of air piping.

Could i place this on the line coming from the pump,before it goes into the tank,to help reduce water from entering the tank?

I don’t know why that wouldn’t work. I have a sailor Belle air compressor and it has 1” x 3’ copper line between the pump and the tank thus cooling the air. When you cool the air the moisture condensates out of the air and then you could use this to catch it before it goes into the tank. Make sure this trap is installed level like it is pictured.

How do i install on pex lines w/o a mounting bracket??? no way to mount to wall/ceiling (and i can't attach to tank)

They make fittings that convert pex to 1/2" or 3/8" pipe thread. I don't know how your running pex without supporting it and not having the tube sag or dip down and collect water.
