VAZ 2114 tank volume: finding out the real numbers

Specifications 2114

Before we look at the main question - how much volume the VAZ 2114 tank holds, let’s look at the main technical characteristics of this car.
Its engine parameters are as follows:

• working volume - 1499 cm3;
• total power - 77 hp;
• maximum rotation speed - 5200 min-1;
• maximum torque - 116 N/m.

In turn, the main operating parameters of the VAZ 2114 car look like:

• acceleration time from 0 to 100 km/h - 14 s;
• maximum possible speed - 157 km/h;
• fuel consumption in urban conditions (per 100 km) - 9.9 l;
• fuel consumption on a suburban highway (per 100 km) - 6.2 l;
• fuel consumption when traveling in mixed conditions (per 100 km) - 7.5 liters.

Now consider the main weight and dimensions of the car:

• total length - 4122 mm;
• full width - 1650 mm;
• height - 1422 mm;
• ground clearance - 165 mm;
• wheelbase size - 2460 mm;
• front track - 1400 mm;
• rear track - 1370 mm;
• weight (curb) - 985 kg;
• weight (total) - 1410 kg;
• fuel tank volume (full) - 43 l.

As you can see from the table above, the gas tank on the VAZ 2114 holds exactly 43 liters. Is this really so? Let’s look at it below.

Actual tank volume on the 14th model

As mentioned, the manufacturer claims that the volume of the 2114 tank is 43 liters (in some cases you can find a figure of 42.5 liters). And this figure is indeed very close to reality.

At the same time, it is worth considering a number of facts that can significantly affect capacity:

1. Errors in the manufacture of the tank.
2. Time of year and temperature.
3. Fuel system volume.

The first of these factors is usually insignificant. But, as practice shows, sometimes the difference in the volumes of two identical tanks can reach (as a result of low production accuracy) 2 liters. Thus, on some machines the total volume can reach 45 liters (which is extremely rare).

This should also include the difference in weather conditions. In cold weather, the fuel contracts, and in warm weather, it expands. This factor also affects how many liters the tank on a VAZ 2114 can hold (if we take into account the full volume of gasoline that can fit in hot summers and winter frosts, the difference can reach 1.5 liters).

Well, finally, you should remember that the fuel system itself also holds a certain amount of fuel. On average, when the tank is completely empty, up to 2 liters of gasoline can remain in it. As a result of this number of features, the amount of fuel contained in the tank may differ from that declared by the manufacturer, either more or less.

If at a gas station you managed to fill 50 liters of fuel into an almost empty tank, then this can become a good reason to complain about the accuracy of the filling device and the operation of the station itself. Such a large difference in volumes cannot be attributed to any of the above errors.

It is also worth noting that if the vehicle is operated incorrectly and refueled with low-quality fuel, sediment can accumulate at the bottom of the tank, which over time can (albeit insignificantly) reduce its volume. In order to avoid such a situation, the tank should be inspected every few years.

If the warning light on the panel lights up, it means you can fill the tank with up to 35 liters of fuel without fear of it overflowing.

Consumption and travel distance

If we take into account the volume of the VAZ 2114 tank and the data on gasoline consumption (given in the table above), we can draw the following conclusions about the possible travel range.

When driving at a constant speed of 90 km/h, the maximum range can be almost 700 km without additional refueling.

When traveling in the so-called “mixed” city/highway mode, consumption will increase, which means the range will decrease (up to 640 km).

And when traveling only in city mode (taking into account standing in traffic jams and a large proportion of driving in low gears), fuel consumption will be maximum - almost 10 l/100 km. It is also worth considering that these figures are for new cars. For used cars they will be slightly higher.

Common FLS malfunctions

Often, the driver can observe the following situation: while driving on a flat road, the instrument panel displays information about a full tank, and after driving off-road, about an empty one. The readings jump, which is clear evidence of a malfunction of the VAZ-2114 FLS. This disease often manifests itself due to wear on the contact tracks.

In some cases, the situation can be corrected quite easily - bend the slider so that it is located above the worn-out place in the diagram. But such a solution to the problem is not always appropriate. Sometimes you have to replace the entire regulator.

Other malfunctions of the mechanism include:

1. The pointer is at zero - most likely the problem is related to the limited travel of the float.
2. The low fuel light does not light up - there may be a problem with the potentiometer.
3. When starting the engine, the indicator does not light up - there is a problem with the electronics.
4. Incorrectness of the data displayed on the instrument panel - you should check the tightness of the float.

If such symptoms of a device malfunction appear, experts also recommend checking all the wires securing the nut sensor. The fastening elements clamp the mass, so if they are not tightened well, the contact will appear and disappear. If the sensor does not show the fuel level of the VAZ-2114, then the contacts need to be cleaned, and if this cannot be done, then they can be completely replaced.

Fuel tank design

The main function of a fuel tank is to store a certain amount of fuel. At the same time, everything must be organized so that the likelihood of a fire hazard is minimized.

On VAZ cars the fuel tank is located under the rear seats. Due to this placement, in the event of serious accidents and car overturns, the tank in most cases remains undamaged. VAZ fuel tanks are made of leaded steel sheets. Thanks to a thin layer of lead that protects against corrosion, the service life of the tank is significantly increased. The outside of the fuel tank is covered with dark enamel.

The fuel tank, covered with dark enamel, is reliably protected from corrosion

The fuel storage volume of the VAZ 2108 and other similar models is 43 liters. This takes into account the reserve, but it is not recommended to fill the tank to the brim. You should always leave a free volume of about four liters. It is especially important to do this in the summer, since the fuel expands as the temperature rises. If the tank is filled to the brim, then after swelling it may simply burst. The volume of the VAZ gas tank is designed in such a way that the autonomous mileage is enough for 500 kilometers, and this is considered a normal road segment in modern conditions.

The tank is securely fixed to the car body using flexible and durable plate-type clamps. Rubber gaskets must be placed under the clamps to ensure a tighter connection.

The tank mounting plates are very flexible and durable

Gasoline is poured through the neck on the right (in the direction of travel) rear side of the body. It is closed with a screw cap.

Main elements of the fuel tank

The neck is connected to the tank cavity through the filler hose. The other two tubes are integrated with a seven-liter separator installed outside the tank and designed to capture gasoline vapors. As a result of wear, the separator may split along the seam and gasoline will begin to leak out. It can be replaced without dismantling the tank. Moreover, you can temporarily cover the separator seam with a gasoline-resistant sealant.

The separator tank holds seven liters of fuel

In order not to remove the separator (it is necessary to dismantle the bumper and filler pipe), experienced car owners simply disconnect the hoses of the element and cut it out with metal scissors. In place of the separator, a fine fuel injection filter is installed, which performs similar functions.

Instead of a separator, you can install a fine fuel filter

Some separators are equipped with a double-acting valve to minimize fuel leakage. The valve admits and releases gasoline vapor. Once in the tank, the vapors condense and thereby reduce fuel consumption.

The fuel system of the VAZ 2112 car is quite simple

The tank of VAZ cars produced after 2000 is equipped with a fuel level sensor (FLS), which regulates the amount of gasoline in the tank and sends data to the electronic control unit (ECU). The sensor is fixed through a rubber gasket and can be easily removed through the rear seat.

The fuel level sensor is installed on all VAZ models produced after 2000

Major damage to the gas tank

When using a fuel tank for a long time, situations arise that require repair. First of all this:

• holes and cracks resulting from mechanical stress and corrosion;
• clogging of pipes and hoses directly connected to the tank;
• damage to the connecting seam at the junction of the tank halves.

Small cracks are usually sealed. This is a rather labor-intensive procedure, but the functionality of the tank can be completely restored. In case of major damage or holes, the tank is replaced with a new one. Dirt gets into the hoses along with low-quality fuel. In this case, the mesh through which gasoline enters the tank may become clogged. Therefore, it must be periodically washed and changed. In addition, you should only refuel at proven gas stations and do not abuse additives to reduce fuel consumption. The weakest point of the tank is the seam, which is constantly subjected to severe stress. This can be avoided if the tank is made in one piece. The fuel tank can also fail due to deformation of the neck, formation of dents after an accident, separation of partitions inside the tank, etc.

How to check the performance of the fuel pump

Often, for those problems for which the car owner blames the fuel pump, other elements of the fuel system are to blame. To establish whether a fuel pump has failed, you will need to know the reasons why it might break.

Causes of fuel pump malfunctions

Most often, the device may fail while the vehicle is moving. The gas pump may simply refuse to pump fuel from the tank to the engine, or a leak may form, causing the device to malfunction. If the power supply is interrupted, the pump stops working completely.

The main causes of fuel pump malfunctions include the following:

• lack of tightness in the pump itself (leakage);
• damage to membrane surfaces;
• the resource of the pump motor has been used up;
• contacts have oxidized;
• wiring or relay problems;
• dirt and debris in the fuel tank, which, along with gasoline, enter the pump.

As you can see, there can be many reasons for a fuel pump to fail.

Dirt deposits on the filter mesh are a common cause of fuel pump malfunctions.

Gas tank protection for Lada X Ray

To increase the safety of the machine in the event of frequent off-road trips or operation on rough terrain, the manufacturer has provided protection for the engine crankcase. The structural element can withstand light impacts, shaking or contact with stones. However, the fuel tank and lines remain open, which can cause breakdown or rupture of the pressure pipe. The factory installed a standard boot on the hoses, but the quality of the design raises questions. In this regard, buyers resort to modifying the bottom of the car. You can buy Lada X-Ray gas tank protection for a price starting from 10,000 rubles. The kit includes the necessary fasteners. You can also replace the standard fuel line casing with a reinforced version. The amplifier installation procedure is as follows:

1. Drive the car onto a viewing hole or lift.
2. Prepare the necessary bolts and fasteners.
3. Using a socket, unscrew the standard suspension bolt of the front part of the tank and attach the additional angle that comes with the protection to it.
4. Using a knife, remove part of the heat shield to loosen the second mounting bolt. Screw the next bracket onto it.
5. Attach the module to the rear axle of the gas tank suspension through a special bushing.
6. Using the supplied bolts, tighten the shield to the installed fasteners and fully tighten the bolts.

The reinforced fuel line module is installed using standard fasteners with original bolts. The design shape is similar to the factory one, which greatly simplifies the installation procedure.

The capacity of the factory tank is sufficient for full use of the vehicle for its intended purpose. The standard design of highways does not imply reliable protection of elements from mechanical damage, but the defect can be quickly eliminated by installing attachments.

Method 2. Using a fuel pump.

You can drain fuel from a VAZ 2114 (injector) without removing the gas tank using the car’s fuel pump. This method is much simpler, but more dangerous. There is a high probability of damage to the fuel pump. Work algorithm:

1. Select a hose of such diameter that it can be put on the fuel rail.
2. Unscrew the nipple installed in the fitting and put on the hose.
3. Ensure that the fuel pump receives 12 V.
4. Pour the liquid into a container prepared in advance.

This method should be used as a last resort, as it is unsafe for the car’s fuel system. In addition, it will not allow all the fuel to be completely drained from the tank.
