1998 FORD MUSTANG fuel filter

ªPremiumº unleaded gasoline is not recommended
(particularly in the United States) because it may
cause these problems to become more pronounced.
If the problems persist, see your dealer or a qualified
service technician.
The American Automobile Manufacturers Association
(AAMA) issued a fuel specification to provide
information on high quality fuels that optimize the
performance of your vehicle. We recommend the use
of fuels that meet the AAMA specification if they are
available.
It should not be necessary to add any aftermarket
products to your fuel tank if you continue to use a
high-quality fuel.
Cleaner air
Ford approves the use of gasolines to improve air
quality, including reformulated gasolines that contain
oxygenates up to 10% ethanol or 15% MTBE.
Running out of fuel
Avoid running out fuel because this situation may
have an adverse affect on modern powertrain
components.
If you have run out of fuel:
²You may need to crank the engine several times
before the system starts to pump fuel from the
tank to the engine.
²Your ªService Engine Soonº light may come on.
For more information on the ªService Engine
Soonº light, refer to theInstrumentationchapter.
Fuel Filter
Your vehicle is equipped with a fuel filter that is
mounted on the underbody.
For fuel filter replacement, see your dealer or a
qualified service technician. Refer to the Scheduled
Maintenance Guide for the appropriate intervals for
changing the fuel filter.

If you replace the fuel filter, replace it with an
authorized Motorcraft part. The customer
warranty may be void for any damage to the
fuel system if an authorized Motorcraft fuel
filter is not used.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel
economy is you, the driver. You must gather
information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel
gauge readings are NOT accurate as a measure of
fuel economy. We do not recommend taking fuel
economy measurements during the first 1 600 km
(1 000 miles) of driving (engine break-in period).
You will get a more accurate measurement after
3 000 km±5 000 km (2 000 miles±3 000 miles).
The advertised fuel capacity of the fuel tank on your
vehicle is equal to the rated refill capacity of the fuel
tank as listed in the Refill Capacities chart in this
ªOwner Guide.º The advertised capacity is the
amount of the Indicated Capacity and the Empty
Reserve combined. Indicated Capacity is the
difference in the amount of fuel in a full tank and a
tank when the fuel gauge indicates empty. Empty
Reserve is the small amount of usable fuel remaining
in the fuel tank after the fuel gauge indicates empty.
The amount of Empty Reserve varies and
should not be relied upon to increase driving
range. When refueling your vehicle after the
fuel gauge indicates empty, you might not be
able to refuel the full amount of the advertised
capacity of the fuel tank due to the empty
reserve still present in the tank.
