2003 FORD F750 fuel tank capacity

Fuel gauge
Displays approximately how much
fuel is in the fuel tank. The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
When refueling the vehicle from
empty indication, the amount of fuel
that can be added will be less than
the advertised capacity due to the
reserve fuel.
The FUEL DOOR icon and arrow indicates which side of the vehicle the
fuel filler door is located.
Speedometer
Indicates the current vehicle speed.
Odometer
Registers the total kilometers
(miles) of the vehicle.

1. Apply a coating of clean diesel fuel to the new bevel gasket and install
it onto the fuel filter housing.
2. Install the new fuel filter element onto the cap. Place the new fuel
filter element and cap into the fuel filter housing. Allow fuel to soak into
the fuel filter element.
3. Tighten cap onto the fuel filter housing until cap contacts the housing.
4. Start the engine and check for fuel leaks.
After changing the fuel filter, the engine will purge the trapped air as it
runs. Engine may run roughly and smoke until the air is completely
eliminated.

Refer to your engine operator’s manual for service intervals and
procedures.
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(s) on your vehicle is equal
to the rated refill capacity of the fuel tank(s) as listed inFuel Tank
Capacitiesin this chapter. 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.
Your vehicle may be equipped with dual fuel tanks. If so, you will have a
selector control. For information on the Dual Fuel Tank Selector Control
refer to theDriving Tipssection in the7.3 Liter Power Stroke Direct
Injection Turbo Diesel Owner’s Guide Supplement.

bottom of filler hole, with vehicle on level ground.
