WARNING: Do not smoke or carry lighted tobacco or open flame of any type when
working on or near any fuel related components. Highly flammable mixtures are always present
and can ignite. Failure to follow these instructions can result in 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 lines or fuel system
components, the fuel system pressure must be relieved. Failure to follow these instructions
can result in personal injury.
