I have the same filter. Works great.

2manyairgunz, do you know what size it is? You can probably find an adapter that would allow you to screw a bleed valve into it. There's lots of good sources for fittings but you'll have to figure out what male thread that is first. Don't rule out a bolt thread to pipe thread adapter. If you have a set of taps try them to figure out the thread pitch. I just bought a strange fitting for a pressure valve that was 7/16"-20 X 1/4"fnpt from Grainger.

Most bleed valves are 1/4"NPT threads so you will have to get a 1/8"NPT to 1/4"NPT adapter.

2many, to me that fitting doesn't appear to have a taper to it like a npt but instead relies only on the O-ring for a seal (ORS. I'd bet its either a SAE bolt or bspp thread.

Maybe something along this line would let you add on a 1/4" npt bleeder. You just have to get it converter to pipe thread first.

I use an Alpha filter also, they work awesome. $279 Yong Heng pump $400 Alpha filter.

Another bleed valve option https://www.nuvair.com/1-8-mnpt-drain-petcock-bleed-valve.html expensive but looks nice.
