flight to test for water and sediment in the fuel system.
The fuel system is gravity-fed with no separate boost
pump.
The fuel flows from the tanks into a selector valve located
on the lower, left side of the cockpit that has four
positions:

Both - The engine is fed by both fuel tanks

Left - Fuel is supplied by the left tank.

Right - Fuel is supplied by the right tank.

Off - Fuel supply to the engine is cut off.
Fuel will flow from one tank to the other when the selector
valve is in either the Off or the Both position. When
parking the aircraft on a slope, leave the selector on
either the left or right position to prevent cross-feeding
and overflowing of the lower tank.
