  There have been a couple of stories about this sort of thing.  This can be a bit confusing to sort out.

  . . . Is this hose pre-pump or post-pump?
  

  
  Your 'flat hose' is pre-pump; between the fresh water tank and the pump and controlled by two Nautilus valves. Reading over the threads in pthamos745 comment . . . general belief for this failure is turning on the Pump when the Nautilus Valves are set to CITY water as both the White and Green Handle valves would be Off so the pump sucks first any hose water then collapses the hose.
  
  Note in this figure how the White and Green are set blocking flow to pump, light blue lines to pump

  I'm 99% certain that happened to me when I turned on the pump but hadn't changed the Nautilus to "dry camping". I was able to squeeze the hose to get it back round again.
