I 3D printed a pickup and then happened to find that someone else had already created some designs. I just used a standard sponge and it seemed to work fine.

I have since purchased the Bilge-B-Dry system just because I like the design and it uses smaller...
I assumed they were all the same but maybe not? Mine appear more like steel than brass so I would say yes as long as they are crimp type. If you were closer I would loan you the tool so you can try it.
I used the sharkbite crimp tool on my 2005 340 and it worked like a charm. I had already replaced the gasket/washer on many connections and they were still leaking. Now after re-crimping there is no more leaks.
Ahh yes my boat only had 4 from the factory, I added the 5th in the middle between the engines. I also moved two of the lights that were mounted on the wall in front of the engines to the "ceiling/bottom of deck" so they shine down because they were blinding me.
Have you determined the source of the water? Is it just any water that gets on to the top of the hinge? I get some water leaking from the lines you have by the green arrow and I believe its just from the dock water hookup. Need to replace the washer/gasket and see if that helps in my case.
Your antenna connection will probably need to connect directly to the TV which has a digital tuner. I doubt that the old DVD player or other old devices will have a digital tuner which is now needed for TV reception.
