This stubby stepped hose can be self made by using suitable pieces of water hose one inserted inside the other. NOTE for this to work you need to ensure that inner (top) hose does not have an "in wall" cloth braiding but it a full solid rubber wall otherwise the coolant will wick and seep up the braid due to the exposed end in the coolant.
All the above will cost very much less than £200.
