WARNING: This page is about a different car, the 2003 Pontiac Sunfire, 2003 Pontiac Grand Am, 2003 Oldsmobile Alero, and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
ALWAYS release fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components. When relieving the Compressed Natural Gas (CNG) fuel system pressure, take the following precautions to prevent fire and personal injury:
- Vent the CNG fuel system in a well ventilated work area.
- Keep sparks, flames, and smoking material away from the area.
- Wear the appropriate hearing protection during the venting procedure. A sudden pressure loss from an uncontrolled gas leak can cause hearing damage.
