I think most water that gets to the drains comes in either through a leaky gas cap or was pumped in with the gas. I
don't think condensation is a big issue. If it was, it would likely affect you more in flight than on the ground as
you climb up into cold air with humid warm air in the tanks.

This has been my experience also, the water mostly comes in from the outside during refueling or a bad filler cap. The
issue with refueling right before a flight is that the water will be in suspension and needs a while to settle out to
the sumps. Is this water in suspension going to cause a problem?
