HONDA 2003 Civic GX - Owner's Manual - Manual (Page 9)

Your vehicle has an identifying
‘‘CNG’’ label attached next to the
rear license plate. Do not remove
this label. This label is necessary for
insuring your vehicle. Driving
without this label may violate the
laws or regulations in some states.
There are two methods of refueling,
fast filling or slow filling.
Fast filling is normally used in fuel
stations for natural gas vehicles. It
takes about three to five minutes to
fill up the fuel tank.
When refueling, you should use a
fuel fill nozzle that complies with
ANSI/AGA NGV-1-1994 standards.
Nozzles are designed according to
their maximum fill pressure: P24 for
2,400 psi (pounds per square inch),
P30 for 3,000 psi, and P36 for 3,600
psi.
Slow filling is done with a vehicle
refueling appliance. Refueling takes
approximately 1 hour per gallon.
Always observe all safety
recommendations and operating
instructions on the refueling
equipment.
Your Civic’s maximum fill pressure
is 3,600 psi (24,800 kPa), so you
should refuel with a P36 nozzle.
Using a P30 nozzle will fill the tank
to the second (3,000 psi) fill mark on
the fuel gauge. Using a P24 nozzle
will not fill the tank completely.
During a fast fill, the natural gas will
be warmed by the refueling process,
causing it to expand and reduce the
amount of fuel you can put in.
