Maintenance 107 Draining Water from the Fuel Tank DANGER Before working on or inspecting a vehicle, set the parking brakes, place the transmission in neutral and block the wheels. Failure to do so can result in unexpected vehicle movement and can cause serious personal injury or death. Water accumulates in the fuel tank in the process of air entering the tank and water vapor condensating. This water will collect in the bottom of the tank and should be emptied out regularly. To minimize the water vapor condensing inside the tank, the fuel level should be kept high when the vehicle is parked. Always fill up the tank at the end of the trip to minimize the amount of air in the tank.
WARNING DO NOT service any part of the fuel system while smoking or while in the presence of flames, sparks or hot surfaces. Failure to follow these precautions can result in fire. Note: When draining the fuel tank, collect the waste in a fuel proof container. Take the drained fuel and water to a recycle or waste management center. To drain the tank, place a container under the tank. Remove the plug in the bottom. Drain fluid until there is only fuel coming out. Install the plug and check for leaks. Note: Always dispose of fuel according to Federal or local regulations. Take all waste fuel to a recycling or waste collection center.
