Fuel Tank

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. Storage capacity of the tank varies with vehicle model. Refer to the supplement for storage capacity. Fuel tanks mounted in pick-up truck models also have a protective steel cover. The cover is designed to protect the tank from damage due to shifting cargo and Ultra-Violet (UV) radiation. Regulations require that the fuel tank and brackets be inspected every three years or 60,000 km (36,000 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 (if applicable). 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. Refer to Fuel Tank Inspection procedures.
