Do you know if your shop has done the AD that requires checking the
drain holes in the ribs? Since Mooney stores it's fuel in the wing
(rather than in a real fuel tank), the fuel needs to run through the
ribs. At the bottom of the ribs there are very small holes. When the
tank gets patched its easy to put your B-2 over these holes and create
a small pocket where fuel (and water) can stay trapped for some time.
Some of these holes should be covered (since they are mating points
that can allow fuel leaks) and others are there on purpose (to allow
water and fuel to run through). I wonder if you might have disloged
some water in your flight. Turning on the pump would increase the
amount of fluid running through the system and maybe move the water out
sooner? Just a guess.
