Thanks for the reply. I appreciate it. Do you know anything about this hull? It's stamped with "F20" but there's not much information that I have been able to find on it.
As for the water, it's definitely possible that I didn't get all the water the first time. I really hope that's what it is. Where the sending unit is, there was no gasket, either when I removed it or when I replaced it. When I removed it, there were bits of caulk and stuff on the bottom of the face of the sending unit that I figured was no good. I cleaned it up really well, making for a nice smooth contact surface. I screwed it back on, and sealed it up with a good amount of silicon. Hopefully the lack of a gasket will be overcome with the silicon. If not, I can remove it and add some sort of gasket.
I can see what you mean about the vent being placed in such a way that water could splash up and get in there. I can also see how it could be possible that someone put a screw into the floor that punctured / pierced the tank. Particularly where the leaning post is attached, that is something I'll need to check for sure.
Thanks for the ideas... I'll keep you posted.
Chris
