WARNING:
Do not smoke, carry lighted tobacco or an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and can be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING:
Fuel in the fuel system remains under high pressure, even when the engine is not running. Before working on or disconnecting any of the fuel tubes or fuel system components, the fuel system pressure must be relieved to prevent accidental spraying of fuel. Failure to follow this instruction may result in serious personal injury.
