Stephen you are a big lad so watch and not over tighten the clips, the said hose is a bit of nightmare to get sitting right, it might not have sitting quite right in the first place, i would just make sure its sitting right, screw driver tight should be tight enough, i would get out and give it some beans close'ish to home and see wot the story is. If it happins again replace them with some Mikalor clips they are the mutts mate []
