WARNING: This page is about a different car, the 2002 Ford Pickup, 2002 Ford Econoline, 2002 Ford Cutaway, and 2002 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
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 fuel system pressure, follow pressure relief procedure. See FUEL SYSTEM PRESSURE RELEASE
in REMOVAL, OVERHAUL & INSTALLATION - F150 PICKUP - NGV article, or FUEL SYSTEM PRESSURE RELEASE in REMOVAL, OVERHAUL & INSTALLATION - ECONOLINE - NGV 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.
NOTE:
Compressed Natural Gas (CNG) may also be referred to as natural gas. Natural gas is lighter than air.
