Why did I even decide to modify the trunk lid of a Chevrolet Niva? Yes, because recently I began to hear popping noises in the fuel tank, the formation of gasoline vapors, which can be very dangerous, and uneven operation of the car engine with significant dips. It is possible that the gas tank cap is to blame for everything, which does not allow the pressure formed inside to disappear.
This means you need to reduce the valve response threshold. Well, the task has been set, now it must be achieved, at any cost.
We unscrew the cover from its place and disassemble it. We remove the ring with the leash, to do this we pick at ourselves with an awl. Then we find a mesh filter in the housing; this also needs to be removed. The same valve is already located under it.
Keep in mind that the spring in the valve is under tension and if you are not careful, either the spring will fly out and hit you in the face, thereby causing injury, or it will not hit your face, but will fly so far that you will never see it again .
We pulled out the spring and inspected it. Yes, its length is standard, but I need the valve to operate earlier, so we take the spring and cut it exactly in half. After that, put the spring back in place and assemble the gas tank cap in the reverse order. I installed it in place and tried to ride it.
At the moment I have been driving like this for a week, there are no more pops in the tank, and no vapors are being formed either. There are still some incomprehensible moments in the operation of the engine, but still there are no big failures like before. But it would seem how you can think about such a harmless thing as a fuel tank cap.
I didn’t even know before that there was a valve there, I thought it was a banal plug, nothing more. But while searching for the cause of the malfunction, I read that a special valve is built into the lid body. And I read about the fact that you need to pull out the spring from there and shorten it, so if it weren’t for the global web, I would have already diagnosed the motor, our specialists would certainly have found something wrong and I would have paid for that repair, which still wouldn't solve the problem.
The fuel tank is the container at the back of the car that stores gasoline.
The Chevrolet Niva is distinguished by increased fuel consumption, typical of an SUV. This is compensated by the larger gas tank capacity.
As a result, the maximum mileage without refueling differs little from that of domestic road cars.
Chevrolet Niva tank design
The gas tank is a welded structure made of sheet steel. This provides it with sufficient strength and safety. Steel is well welded and soldered. This makes it possible to eliminate minor damage to the walls. However, when condensation forms, the internal surface becomes corroded, creating the risk of rust entering the fuel system. Initially, the Niva Chevrolet was equipped with gas tanks manufactured by General Motors. Their factory part number is GM 212301101011000.
Advice: on the spare parts market, tanks made at AvtoVAZ are more often found. Their quality is not inferior to the original ones, and the price starts from 8,000 rubles.
Draining gasoline from the tank of a Niva Chevrolet: is it possible?
Surely each of us has encountered a situation when we need to get rid of excess fuel in the tank. Don't roll it out, but drain it. There can be a lot of reasons for this - condensation, water ingress, diesel fuel was poured in instead of gasoline, and this has happened. Let’s figure out how to drain gasoline from a Niva Chevrolet without removing the tank right now.
When, why and how to drain gasoline from a Niva Chevrolet
Partial draining of gasoline from the tank of an injection car does not take as long and is not as painful as completely draining the tank. However, sometimes situations arise when it is impossible to do without flushing and completely removing fuel from the system. This may only be necessary in cases where the fuel has become completely unusable and has already entered the engine power system.
In addition to curious cases when the tanker mixed up diesel fuel with gasoline, the need to completely drain the fuel may arise when the tank is clogged with sediment, solid fractions (rust, dirt), or water enters the tank in large quantities.
In these cases, you will have to dismantle and wash the gas tank and fuel pump, and change the filter.
Three ways to drain gasoline
In other cases, when it is necessary to drain some of the gasoline, for example, for roadside assistance, refueling a blowtorch or kerosene stove, you can use one of three methods:
- Draining gasoline through the filler neck.
- Removing fuel through the drain hole in the tank.
- Drain using a standard fuel pump.
How to protect fuel from gasoline drainage?
Rising gasoline prices are the only stable process in our changing world.
Accordingly, its attractiveness to attackers is growing. For Chevrolet Niva owners this is a particular problem. The car does not have a fuel filler flap lock, which makes fuel theft very easy.
Various methods are used to protect gasoline from thieves:
- Installing a filler cap equipped with a mechanical lock (coded or keyed).
- Installation of an alarm sensor on the tank hatch.
- Installing a mesh cup in the filler neck to prevent the hose from entering.
There are also more complex methods: moving the filler neck to the trunk or laying a cable holding the hatch. However, any protection only complicates criminals’ access to gasoline, but does not provide 100% protection. Therefore, mechanical tank protection is ineffective without modern alarm systems.
Important: even if a thief fails to break open the hatch or lid, he can use brute force: pierce the tank, fender and gas tank with a blow of a screwdriver or knife.
Three ways to drain gasoline
In other cases, when it is necessary to drain some of the gasoline, for example, for roadside assistance, refueling a blowtorch or kerosene stove, you can use one of three methods:
- Draining gasoline through the filler neck.
- Removing fuel through the drain hole in the tank.
- Drain using a standard fuel pump.
Depending on the amount of fuel that needs to be removed from the tank, we choose one of three methods.
Through the neck
Draining gasoline through the filler neck.
Despite the fact that this method is quite troublesome, it can be used when you need to drain all or almost all of the gasoline.
It is important to remember that under no circumstances should you drain the tank (if it is clean and does not require flushing) . The fact is that the gas pump, located inside the gas tank, uses gasoline both as a lubricant and as a coolant.
If you run the pump dry, there is a high probability of burning it, so in any case, some of the gasoline should remain in the tank to ensure cooling and lubrication of the electric fuel pump.
In old VAZ models, as in most carburetor cars, the tank was located right next to the filler neck. Therefore, it was easiest to pour gasoline with a hose. In the Niva Chevrolet, the tank is located about a meter from the neck, and the filler pipe has a rather complicated configuration. That is why to pump out fuel you will need a hose at least one and a half meters long, or even more .
At the same time, using the primitive method of pumping by mouth is strictly not recommended.
The fact is that modern gasolines that meet Euro-5 and Euro-6 standards contain very toxic additives, and old fuel cannot be called healthy. Therefore, for pumping, it is better to use a special hose with a bulb or a device for pumping out toxic liquids.
It is a hand pump with hoses connected to both ends - pumping out and draining. Such a pump costs a penny and is sold in any auto store. It is not useful every day, but it is a useful thing in the household.
The draining process is simple, the main difficulty is to insert the suction hose through the filler pipe. On the third try it will work for sure. Now you need to lower one end of the hose to the bottom of the tank, and the other into the container. In this case, the capacity should be below the level of gasoline in the tank. We pump out a portion of fuel with a pump, and then it flows by gravity. And that's all.
Yes, don’t forget about safety - no sparks, cigarettes, heating devices, and especially no open fire nearby.
Through a traffic jam
Gas tank drain plug.
Not the best option, but sometimes it helps. Each gas tank has a drain plug at the bottom of the tank .
The difficulty with Shnivy is that this plug is located extremely inconveniently and you can’t do it without a hose either. Yes, and you will have to look for a hose of a suitable diameter. At the same time, gasoline losses are inevitable. While we unscrew the cap and attach the hose, some of the gasoline will be in the sleeves, some on the ground. That is why the following method will be most preferable.
Using a fuel pump
The standard Chevrolet Niva fuel pump will help when it is necessary to drain a small amount of fuel, but more often than not, a liter or a half of gasoline is vital. You can drain gasoline either to the fuel rail or directly from it. In any case, gasoline will be supplied in portions of 150-200 ml .
The action plan is as follows:
- We turn off the engine and open the hood.
- On the fuel rail we find a fitting with which the pressure in the rail is controlled. It is the same nipple as on the tire tube. (Or remove the hose that supplies fuel from the fuel pump to the ramp).
- Remove the protective cap.
- Unscrew the nipple.
- We put one end of the hose on the fitting in the ramp, and lower the other into a clean container.
- We turn on the ignition, but do not start the engine. We just turn on the ignition. In this case, the fuel pump starts working until the fuel pressure sensor operates. During this time, about 150 ml of fuel will enter the container.
- When the fuel pump stops, turn off the ignition, then turn it on again. During the next cycle, another 150 ml will be pumped into the container.
- After pumping out the required amount of gasoline, screw the nipple into place and put on the cap.
When using this method, you also need to remember that under no circumstances should you pump out fuel below zero.
How to replace?
Repairing or replacing a tank begins with its dismantling. Before doing this, it is necessary to completely drain all gasoline and relieve pressure in the fuel system. To work you will need:
- crosshead screwdriver;
- heads for 10, 13, 17.
To remove the gas tank, you must perform the following operations:
- Disconnect the ground terminal from the battery.
- Remove the rear seat.
- Unscrew the screws and remove the fuel pump cover.
- Remove the terminal with wires.
- Unscrew the fasteners and remove the decorative panels.
- Move the sound insulation aside.
- Remove the left and right mounting crossmembers.
- Remove the rear and front fastenings.
- Unscrew the fastenings of the locks and seat belts
- Remove the cover.
- Loosen the clamps and remove the fuel and ventilation hoses.
- Unscrew the front and rear mounting nuts.
- Remove the tank through the vehicle interior.
Installing the gas tank is done in reverse order.
Gasoline drain protection
To protect against gasoline drainage, you can install a reed switch on the hatch, which will trigger an alarm. But in this case, the attacker will drain gasoline under the siren. Therefore, it is better to install a mesh in the fuel line of the gas tank.

Therefore, for pumping, it is better to use a special hose with a bulb or a device for pumping out toxic liquids. Do you still think that diagnosing a car is difficult? The gas tank ventilation system helps prevent problems with vapor accumulation in the tank.
To prevent the tank from deforming due to the influence of changes in pressure, valves are installed in the filler plug. ...
When the key is turned back, the lock unlocks the latches, thereby making it possible to unscrew the tank cap. Removal and replacement The tank is removed if defects occur in it in order to carry out subsequent repairs.
However, sometimes situations arise when it is impossible to do without flushing and completely removing fuel from the system.
The valve is removed in the following order: Open the hood; We find a valve on the fuel line that looks like the photo below; The tubes are removed from both sides and the valve is removed.
Now the product is purged and cleaned, after which the valve is installed in the reverse order of removal. Removal and replacement The tank is removed if defects occur in it in order to carry out subsequent repairs.
If it is not possible to repair the tank, then it is replaced.
To do this, the following actions are performed: Drain the fuel; Disconnect the ground terminal from the battery; The rear seat is removed; The fuel pump cover is unscrewed and the power plug is disconnected; The fuel hoses are removed after loosening their clamps; The ventilation hoses are also disconnected; Using a wrench, you need to unscrew the bolts securing the tape holders, and then slowly loosen the tank; A control check is made to disconnect all pipelines and the gas tank is removed through the vehicle interior.
Thus, the tank is removed from the Niva Chevrolet car and repaired or replaced.
The most preferable option is to replace the product, but it all depends on the budget. Additional gas tank An additional tank is an excellent solution for those who are used to traveling not only in cities, but also off-road. To avoid the problem of running out of gasoline, many owners install an additional tank.
This additional tank is an optional device and is installed only when necessary. The best place to install it is the trunk of a Chevrolet Niva SUV.
Tools:
Based on this, it is worth noting that, first of all, it is necessary to monitor the adsorber sensor, which directly affects the pressure in the gas tank.

With all this, gasoline losses are inevitable. While we unscrew the cap and attach the hose, some of the gasoline will be in the sleeves, some on the ground.
That is why the following method will be more desirable. The standard Chevrolet Niva fuel pump will help in this case, when you need to drain a small amount of fuel, how to drain gasoline from a Chevrolet Niva in most cases, specifically a liter to one and a half gasoline is actually needed. Of course, drain gasoline either to the fuel rail, or directly from it.
As a result, gasoline will be supplied in portions, ml by ml. We turn off the engine and open the hood. On the fuel rail we find a fitting, using which we keep the pressure in the rail under control.
Removing fuel through the drain hole in the tank.

There are still some incomprehensible moments in the operation of the engine, but still there are no big failures like before. To clarify this issue, let's look at the design features of a car tank: Is it possible to accurately determine the remaining gasoline in the tank? The volume of the Chevrolet Niva fuel tank at a single gas station can be filled to a level of 60 liters. But it is impossible to determine how much fuel is left in the tank when the red warning light comes on.
This is explained by the structure of the tank, which has a stamping for the driveshaft.
Gas tank cap
Due to partial communication between the cavities of the fuel tank, fuel in an amount of 5 to 7 liters may remain unclaimed. Experiment To determine the actual volume of the tank, let's go to a service station and consult with specialists. For the completeness and objectivity of the experiment, it is necessary to use a measuring container into which gasoline will be poured from a fully filled tank.
This procedure will allow you to determine how much fuel fits in the tank.
During the experiment, it is clear that the actual volume of the Chevrolet Niva tank is larger than indicated in the data from the manufacturer. Moreover, a certain amount of fuel will always remain in the tank at the bottom between the communicating vessels. Let's summarize Car enthusiasts are often interested in the issue of the capacity of the tank intended for supplying fuel to the vehicle.
In terms of fuel consumption, the Chevrolet Niva car showed its efficiency.

Last night there was l in the tank. thirty-. We relaxed, parked the car and went to bed. In the morning I got into the car and didn’t even realize that the needle was almost zero and the lamp was on. He looked, the tank was closed, there were no traces. Well, that hasn't happened in our backyard in 100 years. I thought about the sensor failure, did a careful test, turned it on several times, turned off the ignition, our client seems to be normal, the needle is moving. I went to the gas station, flooded the 30s, the boom went up, which means that in practice they leaked. I would catch these pioneers and sell them to my ass. I ordered a Foltz lid with a lock for our hack, hope this one is of better quality
