fooseball_movie,

Bruce is correct.

Depending on your airplane, I offer the following:

If the engine and fuel lines are exposed, and most of mine are, I secure the plane, re-start the engine, high throttle, pinch the fuel line and separate it from the engine. This burns the fuel out of the engine faster than the method Bruce mentioned. Then, if it will be a while before flying again, add some drops of After-Run Oil. I use Rislone. Others use Marvel Mystery oil or Transmission fluid, or buy AAO at the LHS. This protects the Ball Bearings.

I do not empty my tank, but merely pull the line off the muffler and connect the two lines from the tank together. This seals the fuel in the tank, as well as if it were in the fuel container.

If the fuel lines are inside the cowl and innaccessible, you can shut off the fuel on most fuelers by inserting the fueling probe. Then follow what Bruce said.

Good Flying,
