WARNING:
Do not modify the system configuration or components, or install new components with parts not specially designed for use with natural gas. Ford Motor Company has specially designed the materials, components, and system configuration for the 5.4L natural gas vehicle, and each particular system is precisely calibrated for efficient operation. The use of different parts or materials can produce an untested configuration that could result in fire, personal injury, or cause engine damage. Failure to follow these instructions may result in personal injury or death.
WARNING:
It is important that the natural gas vehicle be correctly maintained by Ford natural gas trained personnel. If a concern occurs, it is important that correctly trained personnel diagnose the cause. If the problem relates to the fuel system, correct new part installation is imperative to keep the vehicle operating at normal performance. Natural gas components and gasoline fuel components are not interchangeable. If the vehicle is not repaired in accordance with natural gas-fueled vehicle procedures, damage can occur and the warranty may be invalidated. Failure to follow these instructions may result in personal injury or death.
NOTE:
All standard production components and systems receive routine repairs under base warranty procedures.
