Velocity (173 FG) has the standard ~5-gal sump in the belly just forward of the
landing gear bow.  Wings gravity feed into the sump and fuel pump draws from
there.  Asymmetric transfer drove me NUTS for the longest time.  Have it pretty
much under control now, but understand it's a little bit of a common problem.
If you have a sump you gravity feed, use bigger than 3/8 lines.
