tlerm,

I have several Caddis tubes. The pump that is in the first picture will work just fine. I have that pump. If you check the diameter of the pump's hose with the diameter of the valves on the tube they will be the same. Go to a hardware store and buy some clear plastic tubing with the same inside diameter. Put one end of a 4 inch piece on the valve and the other on the hose and you're good to go. The tubing is cheap. Any questions let me know. Have to second the PFD and the force fins. I have a pair of neoprene booties that I wear float tubing that work great. Really didn't like the feel of wading boots while tubing. Good luck.
