Maintenance 103 Changing the Secondary Fuel Filter 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. 1 WARNING Hot engine. Keep yourself clear of all hot engine parts and/or fluids. A hot engine and/or can cause serious burns. Clean around the fuel filter. This is important — if dirt mixes with the fuel from this filter, it will end up in the injection system.
2 DANGER To avoid potential fire hazard, do not service any part of the fuel system while smoking or in the presence of flames, sparks or hot surfaces, or when working on an operating engine. Failure to follow these precautions can result in fire. To guard against burns from direct contact with hot fuel, wear adequate protective clothing (face shield, heavy gloves and apron, etc.) when working on a hot engine. Remove the filter element. Dispose of it in a safe and responsible manner.
