natural gas is ignited, you or
others could be injured. Replace
the O‐ring before filling the tank.
To replace the fill valve O-ring: 1. Carefully remove the O-ring from the groove in the fill valve.
A small flat-blade or pointed
tool can be used.
2. Make sure the groove is clean and free of dirt and debris.
3. Install the new O-ring in the groove in the fill valve. Make
sure the O-ring is properly
seated in the groove.
Refueling will stop automatically
when the tank is full. To disconnect
the vehicle from the refueling station, remove the nozzle from the
fill valve. A hissing sound may be
heard as a small amount of natural
gas escapes. This is normal.
If dirt or other debris is adhering to
the inside of the fuel fill valve, gas
may leak out after refueling. If more
fuel is needed, repeat the refueling
procedure.
