Gas gauge not working? I think I fixed it.

Just when I begin to think that I am finished, it pulls me back in.
I have the new spare tire well on order and have cut the steel for the other rust outs in the trunk, that was covered up with residential carpet cushion.
So I have torn out all the carpet and removing the cushions to find out what else was hidden.
There is rust under the drivers and passengers floor. Driver's side is the worst. Both sides the rust seemed moist, BUT NO rust-outs.

I will treat all spots that has surface rust and paint it. I will find some proper automotive carpet cushions and put them in. I will clean the carpet and then decide if I am going to trash it or reinstall it.

I bought a welder the other day and now have to learn how to use it.
