In detail: fuel level sensor Mitsubishi Lancer 9 DIY repair from a real master for the site my.housecope.com.
You will need: a socket wrench "for 8", a knife.
1. Disconnect the wire from the negative terminal of the storage battery.
3. Using a knife, pry the hatch cover at the base of the body above the fuel level indicator sensor and remove it.
The cover is glued with sealant.
4. While pressing the release tab, disconnect the transmitter harness connector.
5. Remove the three nuts securing the sensor body to the fuel tank.
6.. and carefully remove the fuel level sensor from the tank together with the rubber gasket, taking care not to damage the float and other parts.
Be sure to replace the gasket if it is torn or badly crimped.
7. Install the sensor and all removed parts in the reverse order of removal. At the same time, glue the sunroof cover over the fuel level indicator sensor with sealant.
I started repairing the sensor, like many others, by bending the slider. But not even a year had passed and the problem came to visit me again. This time I had to take a closer look at this issue. The essence of the problem is the wear of the bushing in which the float axis rotates.
Pay attention to how far the slider moves away when the float is lowered (empty tank):
1. Cut out a rectangle from the PCB (3-4mm):
2. At this plate we grind on the large sides of the chamfer. We cut out the clamp in the form of a Chevrolet nameplate from the tin and squeeze the plate along the chamfers so that the metal of the clamp does not protrude onto the plane of the PCB.
3. We put the ends of the clamp under the sensor and fix it with the bracket of the sensor itself.
P.S. The pictures were taken with a phone, so the quality leaves much to be desired, but the meaning of the actions is clear anyway.

The report used materials from the author “mits163”, for which many thanks to him!
I also have a problem with the sensor does not show the fuel level only when the floor of the tank does not go lower, I even bought a new sensor, it is still a problem. Tell me what to do?
First, make sure the tidy is in good working order.
With the ignition switch off, remove the electrical connector from the fuel sensor.
Incl. the ignition switch to the "АСС" position, the fuel level should show a full tank.
Off ignition lock and close the contacts in the electrical connector. In this case, when incl. ignition lock, the fuel level on the tidy should show an empty tank.
Read this thread from another forum and follow the link in this thread:

I tried it all. I'll look in the inside of the tidy thanks for the link.
Hello, I have the following problem with the sensor, after refueling everything is fine, but sometimes the fuel level drops sharply, although there are actually 20 liters in the tank, and it shows an empty tank on the instrument panel, but after a while the arrow rises to the real fuel level. how to deal with it?
From what you wrote, I come to the following conclusions: at a certain level of fuel
(20 liters) the moving part of the FLS periodically loses contact with the stationary one.
Remove the FLS from the tank, check my assumption and if it is correct, try to restore contact in the entire measuring range of the sensor. Perhaps at this stage of the problem it will be enough to simply bend the movable slider in order to displace it from the track worn from long use.
Hello, there is a problem, the fuel gauge works fine until half of the tank, then the arrow drops to zero and the light comes on, but there is still a lot of fuel, I took out the FLS from the tank, I did not find anything, put everything in its place, I can’t start it, who can help.
In your case, it is better to check the sensor not visually, but with a tester. Perhaps, somewhere in the middle, the potentiometer track is worn or broken.
Why the car won't start, I won't tell you. Maybe something else was turned off?
Good day. The problem is this! I bent the slider, put everything in place, but the fuel level is now always from the floor of the tank and above, it does not drop below. There is very little information on the net about this. During assembly, we hooked up the sensor with an electrical connector without screwing it to the tank, they wanted to test it. Whether this could affect the operation of the sensor. Guys, how to be? Help me please?
Haven't tried experimenting as suggested in the second comment?
Good afternoon! The same problem with FLS. At the beginning of the problem, how did I begin to notice the arrows running up and down, and now it does not work at all. At least before the cut-off, fill up. Advise, is it better to chemize or replace?
From the "Lancer Repair Manual":
1. Check the resistance value between
fuel level meter terminal
and the ground terminal when the float
the meter is between the position
"F" (full) and position "E" (empty).
F position = 3 ± 1 ohm
Position E = 110 ± 1 ohm
2. Make sure the resistance is changing
smoothly when moving the float between
position "F" (full) and position "E"
(empty).
3. If the test results match
norm, go to checking the position of
the height of the float of the fuel level meter.
If the test results do not match
ok, replace the fuel gauge
in the tank.
Help solve the problem on the correct installation of the fuel sensor on the tank, on the Mitsubishi lancer 10! (There may be some marks), the sensor shows incorrect readings!
Tell me how to properly fix the fuel sensor on the tank at the moments of creep, on the hairpins (marks)
1. Disconnect the wire from the negative terminal of the storage battery.
3. Using a knife, pry the hatch cover at the base of the body above the fuel level indicator sensor and remove it.

Be sure to replace the gasket if it is torn or badly crimped.
7. Install the sensor and all removed parts in the reverse order of removal. At the same time, glue the sunroof cover over the fuel level indicator sensor with sealant.
Before starting the repair, you need to make sure that the dashboard is functioning normally. To do this, you need to conduct a simple test: turn off the ignition and remove the connector from the fuel level sensor, then turn the ignition key to the ACC position. The sensor should show a full tank. After that, you need to turn off the ignition and close the connector contacts. In this case, when the ignition is turned on, the sensor will indicate an empty tank. If the tidy works, you need to proceed to repairing the fuel level sensor.
A common problem of the ninth generation Lancer is the failure of the fuel level sensor. The problem is in the bushing on which the float rotates. For repairs, a 3-4 mm plastic plate is required. thick rectangular shape. The plate must be wrapped with a piece of aluminum and installed in the sensor body.
