What you heard was the last cone of the last slalom on the last run jumping
in front of my car.

Didja bop any cones?  I thought I heard one in the slalom on the last
straight.

I assume your SUs have floats that hinge on one side.  If so, which way are
your float hinges oriented?  Laterally or longitudinal to the car?  The
better situation would be if the axis of the hinge pin is lateral so that
fuel slosh in cornering would have little effect on the fuel level seen by
the float during cornering.
