Servis Sump hose,
Hi Johnny, has the hose split and leaking, if its intact I would smother it in clear water sealant and then well dry wrap it in duct tape...if bad the hose is in one pierce from the pump to the back of the helmet hose that enters the tub...the helmet tub side is pushed into the tub wall, its a right angles piece of rubber with a hose connector !! It is fiddly but can be done without taking the top off.....otherwise take the wringer off and undo the screws in the sides, the top will pull off but take care with the fibre / rubber top seal that it doesn't break...
Will scan the service pages when back at the weekend,
Have you got a new helmet hose from ebay ?
