What can I use to get water out of a gas tank
The gas tank is out and sitting on the ground. I need to solder a fitting back on without blowing myself up. I've done this before by washing the tank out and letting it sit in the shed for a few days...

91% isopropanol, cheap at the local pharmacy, is soluble in both water and gasoline. So buy two quarts. Drain the gasoline as best you can, throw in the first quart of alcohol and swish around throughly, dump out, then fill with water. After solder/weld, drain, throw in the second quart of alcohol, swish, drain, and fill with gas.
Many years ago, I had to patch a hole in a gas tank with an arc welder. Didn't bother with the first quart/swish but did fill with water, which worked fine and was most helpful in not simply blowing holes in the thin sheet metal with the arc. Alcohol rinse and filled with gas, no problems.
