Leak Testing Before Closing Tanks

I felt it would be prudent to test the tanks in their current state for leaks. There are different ways everyone has done this but I’m just going to do water for now. I filled them up with water and the only leaks I had was my tape job trying to close off the vent line (which I replaced with an aluminum tube going above the water line) and the gas cap (which I just had to tighten it down so it would clamp down harder). So far so good! It seems to be holding water for now. I’m going to give it a couple of days so I can try to rest my leg and get my mobility back.
