Fuel Tank

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.

The CNG fuel tank is constructed of steel and is wrapped in carbon fiber set in epoxy. The high pressure lock-off solenoid is contained within the fuel tank and is used to prevent fuel flow during non-cranking or running engine conditions. Fuel tanks have a protective cover. The cover is designed to protect the tank from damage due to shifting cargo. The cover is not designed to support a load. Federal government regulations require that the fuel tank and brackets be inspected every 3 years or 60,000 miles, which-ever comes first. Fuel tank inspection results should be recorded in the CNG Fuel Tank Inspection Record area of the owners manual supplement. The service life of the CNG fuel tank is 15 years from the date of manufacture. All CNG fuel tanks regardless of inspection results must be replaced after 15 years.
