Largus fuel level sensor 16 valves where is it located

How to find out if there is gasoline in the tank?

Divide the consumption (how did you calculate it?) by one hundred, and you get the consumption per kilometer. After this, you can calculate fuel consumption for any number of kilometers simply by multiplying this figure by kilometers on a calculator (in a smartphone, for example).

Disassembling the module: replacing (cleaning) the fuel filter, fuel pump and fuel level sensor

The fine fuel filter (housing), the coarse filter (mesh), the fuel pump, and the fuel level sensor are located in the fuel module complex, which is located in the fuel tank.
Note: According to the regulations, replacement of individual parts of the fuel module is not provided, and in the event of failure of any of its components, the module is replaced as an assembly. However, in an emergency, to replace the fuel pump, clean the fuel filter, or replace the fuel level sensor, the module can be disassembled.

To disassemble the fuel module and replace parts, remove it from the vehicle. (see here)

Disconnect the fuel level sensor wire block from the cover

Remove the fuel level sensor by sliding it in the direction of the arrow

Fuel level sensor 1 – resistor; 2 – slider; 3 – sensor wire block; 4 – float; 5 – float lever

Using a screwdriver, press out the three plastic clips...

...and remove the glass from the fuel module body. Here is a fine fuel filter (housing) and a coarse mesh filter

Remove the rubber o-ring of the fuel pressure regulator.

The glass contains a fuel pressure regulator 1 and an anti-drainage valve 2 .

Having overcome the force of the clamps, remove the fuel strainer.

Wash, blow out, or replace the strainer

Note: to replace the fine filter, some car enthusiasts used a non-original filter with art. LF249M (see photos and dimensions)

Using a screwdriver, press the cover latch...

. answer the lid to the side

remove the spacer spring

Disconnect the fuel pump block from the connector on the inside of the cover.

Remove the fuel pump from the fuel filter housing.

Note: Fuel hoses are secured to the fittings of the pump and filter housing by heat shrink.

After heating the plastic corrugated tube on the pump nozzle, remove the tube from the pump nozzle. Use a stream of boiling water from a kettle or a hair dryer for this.

Attention : before using a hair dryer, thoroughly blow and dry the parts to avoid fuel ignition!

Note: After removing the hoses from the fittings, it may be necessary to replace the hoses to ensure a good seal. Some car enthusiasts used corrugated fuel pump hoses for VAZ.

To install and secure the hose on the fuel pump after removal, some car enthusiasts use regular clamps (but not the worm type)

11 mm. The clamp must be secured so as to ensure a tight connection and at the same time not crush the plastic hose.

We assemble and install the module in the reverse order.

Some misconceptions about the fuel pump (from Behind the Wheel magazine)

The slightest loss of pump seal will immediately lead to a fire, since its brushes constantly spark.

The gas pump is not a sealed structure, and its internal parts, such as the anchor or brushes, are constantly bathed in gasoline. But combustion is impossible: the concentration of fuel vapors is much higher than the stoichiometric one, and therefore it is impossible to ignite them.

Cars with fuel injection need to be refueled more often, but you can’t drive “with a light bulb” at all.

Many people believe that if the tank is not full, the pump will definitely start sipping air instead of gasoline and quickly die. The pump is placed in a plastic cup that prevents fuel from draining during acceleration and roll. The glass is pressed by a spring to the lowest point of the fuel tank. In addition, internal partitions in the fuel tank prevent the ebb and flow of gasoline. What if the fuel runs out? And there will be no troubles: as soon as the pump stops creating pressure, the engine will stall, and the controller will turn off the power in a couple of seconds.

A motor running “dry” instantly fails.

When the internal combustion engine stalls, power is removed from the electric fuel pump very quickly. Therefore, he does not have the physical ability to thresh for a long time in a “dry” mode. In addition, we ran the pumps “dry” for about ten minutes - and nothing: cold body, low current consumption, even noise. Therefore, the pump will not die from lack of gasoline.

Gasoline plays the role of a lubricant in the electric gasoline pump.

The lubricity of gasoline is negligible. It plays the role of a coolant rather than a lubricant.

Excessive pressure in the fuel line is harmful, so when replacing, it is strictly forbidden to install a more powerful fuel pump.

The bypass valve (pressure regulator) in the fuel module monitors the amount of pressure generated by the fuel pump, sending excess fuel back to the gas tank. Therefore, a more efficient pump will not cause any harm. It’s another matter if you installed a weaker engine than standard: when operating at maximum modes, the engine may not have enough fuel and it will begin to “shut up”.

On cars converted to gas, fuel pumps especially often break down.

There are horror stories on online forums: the gas pump on cars with gas equipment is always running, pushing gasoline in a small circle, and therefore fails more often. But this is a normal mode, no different from a working one. Trouble could arise only if there was a complete lack of gasoline in the tank, but this already resembles sabotage. However, the pumps are also not afraid of short-term dry operation.

It would seem, what is there to talk about? Information about the reserve in the fuel tank should be contained in the vehicle's operating manual. Or even simpler: the trip computer warns about low fuel levels and tells you how far you can drive before refueling. Not always. Others give out only dashes instead of specific numbers, causing you to panic even more.

However, the authors of instructions often limit themselves to general words. For example, “the low fuel warning light comes on when the fuel tank is almost empty.” This is a quote from the Hyundai Solaris and Kia Rio operating manuals. It even contains an element of drama: “Running out of fuel may endanger the occupants of the vehicle.” Scary.

What does the “light bulb” mean?

Lada Largus dashboard description

The Ferrum company could not ignore several cars that were in the top ten best-selling cars of 2014 in Russia.

Thanks to its bright design, the GF 890 dial instrument cluster can become a real highlight in the interior of your car.

Thanks to the 4.3'' display made using TFT technology, the instrument cluster can display 5 parameters simultaneously, which will have a positive effect on the ease of driving.

Installing the electronic combination does not require special knowledge, is simple and can be done by the car owner himself.

Note: on Renault Duster, Duster Diesel, Duster 1.6L, Sandero Stepway, Nissan Terrano cars without a standard on-board computer, displaying instantaneous fuel consumption requires its activation and installation of additional wiring.

Why you shouldn’t delay refueling

Unless you find yourself on a desert island where there are no gas stations at all, then most likely you will have enough fuel. But does this mean that refueling is okay? No and no again.

If you are driving in an unfamiliar area, how do you know when the next gas station will be? So, turn to the first one you come across and fill in more. Remember that you will still have to fork out money. Only if you stop halfway and one of the drivers passing by agrees to take you in tow or drive you for a bottle of gasoline, “refueling” will cost more.

This happened to me once: night, an unfamiliar city, a burning light bulb... I still hope for an opportunity that will suddenly lead me to some gas station. But in vain. The car stops, it’s good that I have time to roll back to the curb. A belated motorist comes to the rescue, and twenty minutes later he brings me a plastic bottle (wow, he managed to pour fuel into an “unregulated” container). I pay for gasoline and, although quite moderately, for services. I consider myself lucky.

We take out the fuel pump.

The fuel pump on Largus is located under the rear seats. In order for us to get to it, we recline (raise) the rear seats - “forward”.

The hatch with the fuel pump is located under a black cover. To move the cover we need to unscrew the plastic fasteners and remove the top plastic casing.

We pull the floor covering a little to the side and the protective cover of the fuel pump is visible in front of us. Remove the protective cover and clean off all the dirt and dust near the plastic nut of the fuel pump

. Now we can disconnect the supply fitting and unhook the connector.

To remove this connector, you need to have a small and thin screwdriver, otherwise you will not be able to bend it. Made a little awkwardly.

This will be the first and smallest difficulty we encountered.
