I broke this part when i was trying to replace the motor, and unfortunately the 2nd hand one i got turned out to be wrong. Anyway put the old one back and apart from the bit i broke it works fine (dammit!).
Thought i'd be clever and take the bit i needed from the other motor and this worked but without some sort of connecting piece the hose won't fit:
This is the piece that came off the hose (sorry not great quality image):
Also does the metal pipe inside the rubber hose run all the way through? I'm fearing i might have to get a whole new hose or do a bit of make-shift repairing.
