It sounds like air.  If the carts were not loaded with a good vacuum, they
could need priming.  I use a modified MIS bottom fill adapter (see
http://www.paulroark.com/BW-Info/Modified-Bottom-Fill-Adapter.pdf -- used
with a syringe) to pull the air out of the outlet when something like this
happens.  For this, I hold my finger over the air inlet (I assume that tab
has been removed) and have the plug into the reservoir removed.  This should
not be needed with a commercially filled cart, but it does occasionally.
