Filler Neck

Highly flammable mixtures present in fuel-related components require people to stay away from smoking and any open tobacco products or lighted flames because it results in potential injury to personnel. Engine shutdown does not reduce fuel system pressure which makes it necessary to drain pressure from the system before working on any fuel lines because accidental fuel spray poses significant fire risks. The first step should be to reduce system pressure followed by unattaching the fuel tank filler pipes to the tank. The first step in tank maintenance requires unfastening fuel filler hose clamps followed by disconnection of the fuel tank filler pipes from their attached hoses. From the beginning disconnect the fuel tank filler pipe through screw removal. An easy way to install new components requires following the steps of component removal in reverse order.

Precautions must be taken when servicing the fuel filler hose because highly flammable mixtures in fuel-related components create a risk for personal injury. Therefore, you must avoid both smoking and carrying any lighted tobacco or open flames while near these components. Thousands of pounds of pressure sustain within the fuel system after shutting off the engine therefore system pressure relief must come first before you disconnect any fuel line or component to stop dangerous fuel spray that creates fire hazards. To prevent accidental fuel spraying you should first reduce system pressure then undo the fuel tank filler pipes by releasing their hose clamps and disconnecting the filler pipes from the hose tubes. Start removal of the fuel tank filler pipe through screw removal. Follow the reverse order of steps used for removal to conduct the installation.

Smoking, carrying any lighted tobacco, or having open flames near fuel-related components.
