It is alive!! But I feel really dumb for not catching a mistake in the library. Doh!! 
So it seems like I had it hooked up correctly all along. I found the mistake when I decided try to add some code to the MultiSerialMega code. When I looked at the code I realized that it was missing half of the original code!! :~ I am running IDE 1.0 for ubuntu and the MultiSerialMega sketch only has code for sending data one way so that is why it was not working. So I just added the rest of the code and it started working. 
Now that I can communicate with the pump I can change the settings. Thanks for all of the help.
