I've narrowed down the leak in the screen washer tube to a connection in the tube behind the air filter. As soon as I spray the back window, it ****es out of this connection in the wire (which is an absolute nightmare to get to). Ive pulled it apart and reconnected and still the problem exists, so im assuming there must be a crack in it somewhere? How much is it to get this bit of the pipe replaced?

can you not cable tie the connection, thats what i done to sort mine out

Its coming out where the two pipes actually connect and it happens even when I hold them together so I suppose theres a crack in it somewhere?
