WARNING: This page is about a different car, the 2002 Ford Pickup and 2002 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Natural gas in fuel system is at high pressure at all times. To avoid injury or fire, release fuel pressure from fuel system before disassembling any fuel system component. To release pressure from system, follow pressure relief procedure. See FUEL SYSTEM VENTING in appropriate REMOVAL, OVERHAUL & INSTALLATION article. After performing fuel system pressure relief procedure, a small amount of pressure 3 psi (21 kPa) will remain in fuel rail, and high pressure still exists in fuel tanks. Prevent combustion from escaping fuel; no smoking, open flames or any kind of arcing.
