This article was incredibly helpful. A couple of points:

1. when removing screws, keep track of where they go, one is longer than the others

2. There is a sixth screw underneath the brush cover.

3. It is VERY hard to get the old hose out. I had to unravel it in sections. It screws in, but might have been glued in originally.

4. If you use the Everbilt Bilge Hose (which does fit) note that it does not include a wire inside to strengthen it, nor do the ribs match the contours of where it is supposed to screw into each end. So you just have to force it in (I used needle nose pliers to pull it through). I also wrapped duct tape around the middle of the hose (do not do this on the ends otherwise it won’t fit into the sleeves) to strengthen it.

On Step 4, it is very difficult to separate the top and bottom half. I had to pry screwdrivers in there to pop it apart, it takes a lot of force. Also, on Step 5, I didn’t totally separate the top from the bottom, there’s plenty of room to work the hose in.
