Hand Pump Which Filter?

So I have one of the the cheaper hand pumps $50 I tried taking my filter lines that I have setup from my compressor but it wouldn't fill the gun not sure why. What filter are you using inline to keep water out of the tank? Thank you for you help and stay safe.

I would expect it will take a few pumps, like YO said, probly fifty or so to fill the filters and get the gauges to start moving but at least you will not have any moisture getting into your gun. Using the hand pump takes deliberate all the way to the top and hold for a second then all the way to the bottom and hold for a second to werq properly. I would use the same set up if it were me but would put the tiny Yong Heng filter before the big one.

What is wrong with your Yong Heng?
