If there's  room,  I'd just cut the end off where it's broke,  and slip a  fuel hose over the outside-   straight out-   

Then  curl it  to meet  (what I assume is the  machine's  hard plastic  fuel return)     
Shouldn't be much resistance there,  a  hose clamp should hold it fine.  

Somebody somewhere  probably has that  quick connector.. this would  buy you some time to hunt it down.  


edit to add-    Google  'fuel line quick connector'      you'll have to get some measurements off you old one.    Napa  shows several  for around 10-12 bucks.   Lot's of  other places to look at too.
