It seems to me that the fuel will slosh in the same direction as the ball,
usually to the right.

If the fuel tanks are full on takeoff -- this should be no problem....  

 

 

Yea, but at the price of fuel, who can afford that!!!!

 

Ahh, More benefits of a wee Lancair with an amply filled header tank.  Wing fuel only as necessary to get to the destination with some remaining in the header.  Ability to empty (completely) both wings in level flight. No difficulty with unporting of wing fuel. Hard to unport the header sump when fuel is low in the header.  No #$%$%^% selector valve that might be switched off at the wrong moment or boost pump procedure when switching since there is no selector.  Easier aerobatic control with header fuel only.  Slip or skid to your heart's desire.

Emergency "Sudden Quietness" Checklist UMP:

 

No fuel in the sump,

No fuel for the pump!

My throat's got a lump,

My life's in a slump.

Can't stop altitude's dump.

Gotta fly by my rump!

Set'er down without a bump....

Don't wanna hear "KARRUMP!"
