Dave,
There has been instances, one in particular ( local airstrip) where a couple
of chaps filled the tanks with fuel the night before a big trip.
Some idiot ( local youths) siphoned out the fuel and replaced it with
water.The tanks weren't checked the next morning.
The story goes they had enough fuel to get airborne.
I would always have drain plugs in, even though I agree a little water won't
hurt. I'm sure the daily driver gets plenty of water when he fills up at the
local garage.
George ( down under)
Tom, the pickup is in the lower rear corner of the tank. I would let it
sit overnight to be sure all the water had time to collect (traverse the
entire tank). Most of that glob will be sucked up as soon as I turn on the
pump, but you are right that some additional amount may get sucked up when
the tail comes up, so I will be careful. Perhaps a taxi only test.
The point of this test is to show that the 50 gph of fuel flow is enough
to mix in any water. If I can't pass this test with flying colors, then I
need to put the drain plugs back in.

with alcohol and expect it to mix in? If it doesn't mix in and just
sits on the bottom in a glop, when are you gonna conclude that you've
consumed it and it's not just sitting off somewhere on the bottom? (other
than the engine sputtering and going quiet)

rear of the tank until you got the tail up.

a little magic. Next time I get the chance, I am going to POUR one full cup
of water into my gas tank. I will let it set overnight. Then I will attempt
to start the engine without draining the fuel. If my magic works, the engine
will start an run just fine after a few seconds of running the pump. If the
test fails, I will put the drain plugs back in (and eat a crow).
