That bastard water pipe !

[mark g]

Sorry unfazed it's the outer metal water inlet pipe that feeds the pump, it bolts on the side of the crank case just in front and below the gearbox sprocket, it's got a single large O ring to seal it, the whole affair is only held in by a single Allen head bolt. It should be a piece of piss to fit but I'm having a right game with it, I'll try and post a pic of one I found online
