Inflating a Caddis

What am I missing here? How do I inflate this thing???

I just got a new Caddis float tube, for my 8-year old son. I think the seat is going to be low and perfect for his shorter legs to dangle and kick in the water.

I have an Airhead dual-action pump that has several attachments, but none of them seem to "fit"!?!?

Am I missing an attachment? If yes, how can I get one? (without having to buy a whole new pump)

You need to use 2nd hose, fit it over one of the fittings and slip it over valve on the tube. That's what I had to do

Or call me if you want

that's what I figured.. just making sure I wasn't nuts.

I got it to work, by holding the closes attachment together to the valve really tight.
I'll get a tube to bridge the connections. Thx Miller

No problem buddy, I think the hose I use is 1/2od.

I am sure you son is going to have so much fun out there. I use the largest end of the pump and hold it in place will using the other hand to pump. Does that make any sense at all not sure. But the tube looks good have fun out there.

miller is right. buy a 1/2 inc. pice of tubing at home depot. actually i just cut 3 inches of it and didnt charge me
and it fits tight over the tube valve and the attachment

I got a piece of tubing. It's a bit rubbery, but should work fine. I have it stuck on the air pump adapter already. I'll just leave it on there, since my Cumberland uses a different adapter for the Boston valve. Looks like I'm all set!!
