Cap off all fuel and vent ports, install fuel cap, and fill with as much water as possible. (maybe add food coloring). Put tissue paper on outside of tank rivet lines to "detect" any possible water leaks. Let sit 24 hours max?
Once successful I can drain, clean and dry tank before installing baffle. At this point I can do an air pressure test as recommended by vans (Balloon test?)
If that is successful, I will declare success until just before first flight when I will hopefully be able to test with 100LL (or whatever replacement comes out. HA!).
Don't have any way to store 100LL in my garage and don't want to put a large quantity of fuel in an open container (unfinished tank) for any length of time. Don't want all those gas fumes. Totally see the points others have made, but not sure it's practical (at least for my situation).

Brian, at least go to the grocery store and buy bulk RO water with less than 10 PPM TDS water, it will be the safest. Some ground water is so bad that entire communities use RO treatment. You can buy a TDS meter from freshwatersystems.com. Dasani bottled water is 125 PPM --to much. My local Kroger store has bulk-by-the-gallon water and it is 5 ppm.
