FUEL GAUGE
The fuel gauge in your NGV behaves similarly to a typical gasoline fuel
gauge. However, the gauge operation is based on the pressure and
temperature of the natural gas, not on the level of liquid gasoline.
Depending upon application, a fuel gauge reading of Full will occur at a
pressure of approximately 20 700 kPa (3 000 psi) or 24 800 kPa
(3 600 psi), at a temperature of approximately 21°C (70°F). The NGV
fuel gauge will provide a linear reading from this point down to Empty.
Refer to the Fueling section of this supplement for more information on
fuel gauge performance during the fast-fill method of fueling.
