Which is an old wives tale. The amount of water contained in 20-30
gallons of air is insignificant.

Just let those tanks inhale and exhale a few times. They do that
every morning and night so there is a *lot* more than 20-30 gallons
involved.

So I'd agree the condensation thing is an OWT, certainly with the fuel


It all depends.


capacities of our planes (the biggest capacity wise that I've regularly
flown are an S-35 Bonanza (74 gal usable) and the Geronimo-mod Apache

I fly a Deb with about the same fuel capacity (not counting the tip
tanks). With half tanks and the plane hangered for two weeks in the
Spring, I drained over two full samplers of water out of one tank and
a half out of the other. None out of the auxiliaries as they were
full.

(which carried 7 hours of fuel - I don't remember the exact figure in
gallons, but it was a little over 100 gallons capacity in 4 tanks).

The Deb will carry 100 when the tip tanks are full.

With the Geronimo, because it only has 160 hp a side, it's quite
important not to lug around excess fuel.

I'm paranoid about fuel, particularly with Michigan weathers tendency
to change rapidly. I might go for a 50 mile jaunt, get a late start
back and end up in Wisconsin, or Kentucky.

I rarely go any where without full tanks, with the exception of the
tip tanks.
