okay, so I think I'm beginning to understand about this cone. 1. it's seperate from the basic impeller section that most people replace when they talk about replacing their wp. 2. You won't know until you remove the impeller section if the cone is defective or not. 3. If it is bad, the only recourse is replacement of the complete wp assembly with the Ford unit, the one that comes with the hoses, etc.
Is that it?
