The fuel level sensor, and in vehicles with a DOHC gasoline engine also the fuel pump, is located at the top of the fuel tank.
The diesel engine has only a fuel level sensor without a fuel pump; fuel is pumped by the high-pressure fuel pump.
As the fuel level drops, the float in the fuel tank drops. At the same time, the potentiometer connected to the float increases the resistance of the sensor. As a result, the voltage on the indicating device drops, and the fuel gauge needle on the instrument panel moves in the direction of leer (empty). Depending on the vehicle's equipment, when the fuel level drops to the reserve level, an additional indicator lights up on the instrument panel.
Warning: No open flames, have a fire extinguisher ready and strictly follow safety regulations when working with fuel supply systems, see previous chapter.
Removal
Disconnect the negative (-) battery cable.
Caution: When the battery is disconnected, the contents of electronic memory devices, such as engine fault codes or radio codes, are erased. Before disconnecting, also read the instructions in the chapter "Removal and installation the battery".
Remove the fuel tank, see next chapter.
Using the special FORD tool 23-014/23-026, turn the fuel level sensor holder counterclockwise "arrow". If the tool is not available, loosen the sensor holder using a pipe wrench or lightly tap a hardwood block with a hammer.
Caution: No sparks should be produced, otherwise a fire may occur.
Pull the level sensor holder up, tilt it to the side and remove it. In doing so, place rags underneath to absorb any leaking fuel.
Installation
Clean the sealing surfaces of the fuel tank and fuel level sensor holder from rust and dirt.
Caution: No contaminants must enter the fuel tank.
Attach the fuel level sensor holder with a new sealing gasket.
Tighten the fuel level sensor holder by moving it clockwise.
Install the fuel tank, see next chapter.
Connect the ground (-) cable to the battery.
If available, set the clock and enter the radio theft protection code.
Check the operation of the fuel level indicator on the instrument panel.
