The Jabsco Electric Conversion (the tall cylinder on the right) in the head of my Freedom has a couple of issues. As you can see in the picture, it is rusting/flaking, and also appears to be a small leak at a seal in the bottom. The leak is very minor and appears to only be the inlet water. Has anyone replaced this on their own? If so, how difficult is it? I have the tools, and decent with diy work, but not sure I want to take this on.
