I have this problem with my Genesis 2 (both water and "other" fluids).

Does this come from a "venturi" effect of air leaking from Horz/Vert
Stab Junction or poor Rudder Sealing? *It amazes me how much gets
sucked back into fuselage. *(Genesis has VERY short fuselage)

Another Genesis owner (DK) has experimented with an exit duct out the
fuse hatch over wings. ... comments Don???

Likely due to pressure recoveing over the very short length of
fuselage and large reduction in cross section
over that length. High location closer to centerline would probably
better in order to avoid effects on root fillet
area.
Just speculating- It's cold here.
