Lisa - glad I could share in the embarassment!

This is my pump:

Stacie - I have that same pump. It's our 4th pump in 2 years because all the other ones we've tried had issues. So far, this one is great though!

There is no adapter...both types of valves fit into the opening and work on the fly. You do have to get the hang of getting the skinny presta valves in the opening correctly. I've been using it for months and I still occasionally get it on where no air goes in. When that happens, start over. Use a firm hand, but don't jam it on there. Keep practicing and you'll get it!
