If you think it might be a flow problem:

(Do this on a warm day.  You're gonna get WET!)

Disconnect several hoses.  Run a water hose out to
the plane and stick it into the end of each
disconnect.  Try both directions.  Use a rag wrapped
around the end of the hose to make a seal.  All the
components should flow better than the water hose. 
You should be able to tell which component is
restricting the flow.

Have you tried that already?
