The top hose connecting to the hard plastic down pipe has blown off twice. After refitting it yesterday it blew off again after only a few miles. I know it’s a fiddly job but I thought I’d pushed it on securely but obviously not!
Is there any special ways / tricks in refitting it correctly? I was thinking of taking the top hose and plastic down pipe off completely fitting them together first, then refitting the pair together, at least I’ll be able to see that they are fitted together well before replacing them. Do you think this is a good option? Cheers

Is the clip behind the wider section at the end of the pipe?
