I am in the process of making this upgrade and when I took out the old manifold out I noticed that the tank hook ups have a tapered end which looks like it can be cut off to create a wider opening. When you guys upgraded your systems did you cut them back to the bigger opening? I tried to upload a photo but it says the folder is full??
I also learned that I should have looked closer when I bought the boat to check if it had ever been stored with water in the hull.
