UrS4 brake hose swap and fluid flush

[Wylie Bean]

Planning to swap all 4 rubber brake hoses for new rubber hoses and was going to flush fluid at the same time.  I am trying to get the rear hose off at the hard line and don't seem to be making any progress.  
Tips?  Suggestions?  I am without a torch to heat the connection...
