So, the last few days have been spent making bigger inspection ports in my port fuel tank to facilitate putting a sealant in it.
In my next post (from my cell) I will post the pictures that show I had water coming in from the vent fitting. I have previously said that I had already changed the vent hose from outside to inside.
But the pictures also seem to indicate that the screw holes had rusted and rain water was getting into the tank from the top of the tank.
That also explains why when I purposely overfilled the tank by 10 gallons, I had fuel get out, though it did not happen with the stb tank (now, if you ask why I did it in the first place, the answer, as simple as it sounds, I wanted to see what would happen. I'm a scientist after all).
I will also be writing of all the work that was done this winter with before and after pictures.
