Chinese hand pump suggestion.

I received the one with the in-line filter at the quick connect end. It would not fit my Maximus Hunter without removing the TKO. After a quick look and trial fit, I moved the quick connect to the other end and screwed the filter into the pump. I only dead-headed it after this, but it seemed easier. Any input is welcome.

I just raised the TKO and the muzzle up a little and shoved the Foster fitting on.
The TKO rests on the fitting but this works for me.
