Hi Heather- I took a look at your model and see that in the World tab that the procedures for the 2 new pumps are not 'called' in the setup code. Go to the procedure draw and pull out 2 new 'call' blocks and put them under the 'make pump' block. You'll be able to select the 2 new procedures and you should see 2 new pumps.
It's a tricky thing to realize that once a procedure is made that it needs to be 'called' in either the Setup or Forever event blocks.
best of luck,
