2001 Ford F-150 Draining-Coalescer/ Pressure Relief-Natural Gas Bi-Fuel System Repair Manual

1. Relieve the Bi-fuel system fuel pressure. For additional information, refer to Pressure Relief—Natural Gas Bi-Fuel System. 2. Raise the vehicle on the hoist. For additional information, refer to Section 100-02. 3. NOTE: There is an O-ring attached to the drain plug. The O-ring must be replaced each time the drain plug is removed. Remove the drain plug. 4. Install the drain plug. 5. Lower the vehicle. 6. Pressurize the fuel system. WARNING: It is important that your bi-fuel vehicle be correctly maintained by Ford bi-fuel trained personnel. If a concern occurs, it is important that correctly trained personnel diagnose the cause. If a concern relates to the fuel system, correct part replacement is imperative to keep your vehicle operating at normal performance. Bi-fuel components and gasoline specific components are not interchangeable. If your vehicle is not serviced in accordance with bi-fuel service procedures, damage can occur and your warranty may be invalidated. WARNING: Fuel supply lines are always pressurized. When servicing fuel related components, do not smoke or carry lighted tobacco or an open flame of any type. Flammable mixtures may be present and can ignite, resulting in personal injury. WARNING: The natural gas fuel system is always pressurized to 655 kPa (95 psi) downstream of the fuel pressure regulator and up to 24821 kPa (3,600 psi) upstream of the fuel pressure regulator. Use care when servicing the fuel system or personal injury can occur. WARNING: The natural gas fuel supply manifold is pressurized to 655 kPa (95 psi). Fuel pressure must be relieved prior to any fuel system service. WARNING: The fuel system pressure must be relieved before any component can be removed. The fuel tanks must be evacuated prior to tank removal. Removal of components without pressure relief or tank evacuation can cause natural gas to escape into the air and cause injury or death.
