thanks - i'm really torn with which way to go at the moment, the dye was actually under the rubber sleeve on the bend aswell as the snap fitting, the pipe is still holding pressure (no baths in our house tonight!) will air not leak when gas will? - i'm leaning towards changing the pipe. Just to add a curve ball - I/we have two galaxy's, we're off on hols next month and the wife wants the aircon working - fair enough - I start to repair galaxy 130 (cruise control!). 20mins ago she declares that we will need to drag the trailer with us - guess what - the 130 doesn't have the towing bracket! - oh joy. I'm thinking holiday without wife or trailer!
