Maintenance 101 Fuel System Service Changing the Primary 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. The standard primary filter is manufactured by Racor. Use only the 30 micron (red coded) element. Failure to do so could result in reduced power. To replace the primary fuel filter element: 1 WARNING 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. Open the drain valve and drain off some fuel into a container. Use a strap wrench to remove the filter cartridge together with the bowl.
