Any tips or suggestions? Can someone who knows how to weld fix that?? Not looking for a perfect restoration, but would like for it to look decent, if not correct.

I have had this same problem a number of times.
I empty the fuel from the tank and rinse it with water (many times ( I have been known to set the tank in its upright position, stick the garden hose down into it and just let it run)) then empty the water from the tank.
Once I am
Sure that there are NO fumes in the tank, I screw a 1/8" inch pipe nipple (about 3" long) into the opening in the bottom and clamp a small pair of vice grips onto the nipple (kinda like a handle).
With one hand, I hold the vice grips so that the small square piece will not move from its place. Keeping the propane torch moving, I heat the small square piece until the solder is melted, remove the heat and hold in place until it cools.
Do not heat the metal of the tank, just heat the small square piece. If you heat the metal of the tank it will warp and then it can be a bear to get it straightened out and soldered back again.
I have only had to add solder one time. That was the one that I warped...
