Cessna C182Q Fuel Selector

[36050100]

The Normal Operations chapter of the POH states that when securing the aircraft after use, the fuel selector must be selected to the RIGHT tank.

Does anyone know the reason for this?

The selection of the right tank isolates the two wing tanks from each other. This will prevent crossfeeding between the tanks if the airplane is not parked perfectly level. In the "both" or "off" positions, the fuel can pass right to left tank through the selector, and will by gravity. A fuel imbalance is possible, to the point where all of your fuel could end up in only one wing tank, and if left wing down, the excess fuel will vent out the left tank vent, and be an expensive, hazardous puddle on the ground under the left wing. If you're by yourself, and your half tanks fuel load has crossfed to the left tank, the plane will be miserably left wing heavy to fly.

A follow up question if I may; would selecting the LEFT tank also isolate the tanks from each other?

[Pilot DAR]

Yes, left or right, same effect. The POH for the 182Q says left or right position.
