Relieve pressure in the power system (see Fuel filter replacement).
Disconnect the wire terminal from the "negative" terminal of the battery.
In the passenger compartment, raise the rear seat cushion.
Using a slotted screwdriver, pry the cover of the fuel module hatch..
... remove the cover.
To disconnect the engine management harness connector from the fuel module cover connector…
... we shift the blocker of the block of the wiring harness of the engine management system (orange color) …
... and by pressing on the latch at the back of the wiring harness block..
... remove the block.
We squeeze the retainer of the tip of the drain pipe..
... and remove the tip of the tube from the fitting of the fuel module cover.
Similarly, from the other fitting of the module cover, remove the tip of the discharge line tube.
Using a slotted screwdriver, turn the locking ring of the fuel module cover counterclockwise until the grooves in the ring and the protrusions in the fuel tank flange match..
... and remove the ring.
Remove the fuel module from the fuel tank opening.
The connection between the fuel module cover and the tank opening flange is sealed with a rubber ring.
To replace the fuel gauge sensor and the fuel reserve warning lamp resistor…
... by pressing the lock of the wiring harness block, disconnect the block from the connector of the fuel module cover.
To remove the sensor and resistor, it is necessary to remove the tips of their wires from the block of the wiring harness (the sensor has blue and white wires, and the resistor has yellow and gray wires).
We mark the location of the wires in the block.
Through the two holes of the pad (shown by arrow) alternately press the awl on the protrusions of the latch of the wire lugs..
... and with pliers we remove the retainer of the wire lugs from the block.
With an awl or paper clip wire, we squeeze out the tongue of the block that holds the tip of the desired wire..
... and remove the wire tip from the block.
Similarly, we remove the tips of other wires from the block.
To replace the fuel reserve indicator lamp resistor, remove it from the retainer..
... and remove the resistor by pulling its two wires through the hole in the module case.
To remove the fuel gauge sensor..
... prying with a slotted screwdriver, remove the sensor and resistor retainer.
Pry off the sensor with a screwdriver..
...we move it along the guides of the module case..
... and remove the fuel gauge sensor, leading its wires through the hole in the module case.
We assemble and install the fuel module in the reverse order.
If the sealing ring of the module cover fails, replace it with a new one.
When installing the fuel module in the tank, we combine the cutout in the fuel module cover with the tongue on the flange of the tank opening.
Before closing the hatch cover in the floor of the body under the rear seat, it is necessary to check the tightness of the fuel module connections.
To do this, connect the wire terminal to the "negative" terminal of the battery and turn on the ignition.
