Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fill Valve & Fill Line
The fill valve receives fuel from the fill nozzle at the CNG dispensing station. The fill valve seals to the dispensing nozzle with an "O" ring. The "O" ring must be inspected and replaced if missing or damaged prior to re-fueling. The fill valve contains an internal 380 micron filter element designed to trap contaminants. This filter must be periodically inspected and cleaned. The fill valve mounting location varies with vehicle model. Refer to the owners manual supplement for fill valve location and fuel tank filling procedures. The fill line is constructed of stainless steel line. The fill line connects the fill valve to the fuel tank and is sealed to the fuel tank with an "O" ring.
