I have a ’99 9-3 convertible. Common problem as I understand, one of the soft top hydraulic hoses has failed (large split, gushes hydraulic oil). With the help of the WIS I’m confident I can remove the hose attachment at the cylinder. However, I have no idea how to remove the hose attachment at the pump. The fitting is crimped on. All the information I have seen says simply “connect the hose”. As the pump is very expensive, I want to make sure I disconnect the hose without damaging the pump. Any help would be greatly appreciated!
