Caution: Do not drain the fuel into an open container. Never store the fuel in an open container due to the possibility of a fire or an explosion.

Caution: Drain the fuel tank to at least 3/4 of a tank before removing the fuel sender retaining ring or fuel sender access panel in order to avoid possible fuel spillage. Failing to follow this procedure could result in personal injury.

Notice: Drain the fuel tank with a hose which has a 13 mm (0.5 in) or smaller diameter in order to prevent the drain hose from getting stuck inside the fuel tank filler neck pipe check valve. Damage to the check valve may result.

Notice: Drain the fuel from the complete system, including injector nozzle(s), the fuel pump, all fuel pipes, and the fuel tank if a vehicle is to be stored for any appreciable length of time. Draining the fuel will prevent the formations of fuel system deposits.
