Where can I get another Zodia zoom air pump fitting? I have the one that came with the foot pump that I attached to my 12volt pump but I need one for my hand pump. My NARU valves from my kaboat work a little but they don't push the center part in and it's really hard to pump unless I open the valve all the way but when I disconnect I let alot of air out. I'm sure I could prob rig one of those by running a paper clip through it or something. Thoughts?
